Reflections on the Miracle of Democracy at Work in the Greatest Nation on Earth

Presidential election minus 10 days

Since our previous episode we’ve had individual polls from red states Georgia and Montana showing Barack Obama narrowly in front, so they’re now included in the polling aggregates. However, John McCain leads in both due to the overall polling picture from the past few weeks. The other remarkable development has been an Obama blowout in Ohio, underscoring a picture of Democratic strength in the rust belt states.

Obama McCain Sample D-EV R-EV
Michigan 54.7 39.4 3005 17
Washington 54.9 40.1 3379 11
Maine 54.5 40.0 2185 4
Minnesota 53.3 41.8 3677 10
Iowa 52.6 41.7 3530 7
Pennsylvania 52.2 41.7 5505 21
Wisconsin 51.5 42.1 3490 10
New Hampshire 51.5 42.3 3305 4
New Mexico 50.5 43.3 2927 5
Colorado 50.8 44.3 3450 9
Virginia 50.9 44.7 3777 13
Ohio 48.7 43.0 4337 20
Nevada 50.0 45.4 3418 5
Florida 48.2 45.3 5021 27
North Dakota 45.5 44.7 1206 3
Missouri 47.4 46.5 4050 11
Indiana 47.4 47.0 3828 11
North Carolina 47.2 48.9 4564 15
Montana 44.8 48.7 2628 3
Georgia 45.6 50.0 3530 15
West Virginia 42.7 51.0 3622 5
Others - - - 175 137
RCP/Total 49.9 43.9 - 363 175

So who’s going to win then? The polls of course leave little room for doubt. However, there are a couple of items of conventional wisdom floating around which suggest they might not be telling the full story, one way or another.

The Bradley effect. A compelling paper by Dan Hopkins of Harvard University examines the popular notion that polls overrate the performance of black candidates in biracial contests due to white voters’ reluctance to appear illiberal when interrogated by pollsters. Hopkins finds the effect was a serious factor into the 1980s, most famously when black Democratic candidate Tom Bradley failed to win the Californian gubernatorial election in 1982, but has ceased to be so. Pew Research charts a corresponding decline in the number of respondents willing to admit they would not vote for a black candidate, from 16 per cent in 1984 to 6 per cent. Hopkins notes a very sudden decline in the Bradley effect (he prefers the “Wilder effect”, after Virginia Governor Douglas Wilder) “at about the time that welfare reform silenced one critical, racialized issue”.

The reverse Bradley effect. Strictly speaking, a “reverse Bradley effect” would involve voters telling pollsters they were voting for McCain or were undecided when they were in fact set on Obama, which is plainly not on the cards. Far more likely is that turnout of black voters is being underestimated in pollsters’ determinations of “likely voters”, which in many cases go on whether they voted last time rather than what they say they will do this time. Whatever methods are being used to account for the certainty of higher black turnout, I’m pretty confident they are overly conservative. When a pollster is required to explain inaccuracy after the event, “I was going on past experience” makes for a more professional sounding excuse than “I made a wrong guess”. I haven’t studied this systematically, but the one example I have looked at has proved to be an eyebrow-raiser: the most recent SurveyUSA poll of Pennsylvania has 10 per cent of black voters among its overall sample, whereas this paper from the Joint Center for Political and Economic Studies tells us it was 13 per cent in 2004. Nate Silver at FiveThirtyEight provides support for this and related impressions in taking to task pollsters who have gaps of 4 to 6 per cent between results for “registered” and “likely” voters.

The late Republican surge. I recently heard it said that Republican candidates tend to come home strong in the last week or two of campaigning. Remembering how much of Bill Clinton’s lead vanished shortly before the 1992 election, I thought this sounded plausible and went burrowing through the archives for evidence. The following chart plots the last 15 days of polling at presidential elections from 1992 onwards, day 15 being the election result. I have used composites of polling obtained from Real Clear Politics for 2000 and 2004; Gallup tracking polls for 1996; and a list of various pollsters’ results I found in the New York Times for 1992.

The case of 1996 stands out, but this might well point to a general inaccuracy in the Gallup series I was using rather than a late surge to Bob Dole (unfortunately I could only locate one poll from the final week). Beyond that, the chart provides pretty thin gruel if you’re in the market for a McCain comeback in the last 10 days. The 1992 Bush recovery was less dramatic than I remembered it once I removed Gallup from the equation, which exasperatingly shifted from “registered” to “likely” voters in the final week, eliminating much of Bill Clinton’s lead at a stroke. If anything the trends from 2000 and 2004 point the other way.

Front-runner decline. The aforementioned paper on the Wilder/Bradley effect by Dan Hopkins informs us that polls “typically overstate support for front-runners”, which is demonstrated in the scatter plots under “Figure 3” (see right at the back). These suggest a candidate like McCain who is on about 42 per cent is probably being underestimated by as much as 2 per cent, while a candidate like Obama on 50 per cent is probably being represented accurately – unless he’s black, in which case he will suffer a Bradley effect of a bit over 1 per cent.

Advertising. The Washington Post informs us that the cashed-up Obama campaign is fielding “as many as seven commercials for every one aired by Republican Sen. John McCain”.

My guess is that point one will be comfortably countered by point two; point three is worth little if anything; point four might help McCain close the gap by 2 per cent, but some of this gloss should be taken off after accounting for point five. In sum, there seems little reason not to take the polls more-or-less at face value. That being so, my final prediction is that Obama will win every state where my polling aggregates currently have him ahead except North Dakota, where the result is derived from two small sample polls, one from an agency of little repute. The margin in Florida is narrow enough that front-runner decline might be expected to account for it, but I find it hard to believe Obama would fail to carry so marginal a state when he’s up by eight points nationally. That makes it 375 electoral votes for Obama and 163 for McCain.

    Adam, You are a veritable fountain of gerrymander knowledge, in comparison with which I am but a mere bubbler!

    The district in your 198 post is not quite as terrible as it looks because the corridor going west from Pomona is a “pass” through a hilly region which my VW Beetle used to find most troublesome during the Punic Wars.

    As you say, there’s plenty of “natural” ethnic concentrations in California, especially in the “barrio” areas in East L.A.. (check out Mexican-American Cheech Martin’s hilarious video clip parody of Springsteen’s “Born in the USA”).

    Not all states have gerrymandering. It depends on whether the state legislature in question decides the boundaries itself. For example, the boundaries of Iowa’s 5 congressional districts are decided independently.

    I know some states actually have elected panels to decide electoral boundaries.

    One of the propositions in California going to vote on the 4th is to replace the elected system with a system where a panel are randomly selected from the voter pool of Democrats, Republicans and others.

    Yes but Iowa is 99% white so the issue hasn’t arisen. If Iowa was 20% Black, and the commissionm drew boundaries that didn’t create one Black-majority district out of five, Black activists would take the commission to court, the courts would follow the Supreme Court’s precedent, and the Iowa legislature would then be forced to gerrymander a Black district. The Repubs would support this for the opportunist reason that the other four districts would then be all-White.

    Here’s an interesting blog post regarding how so many counties vote for either Presidential candidate in a landslide:

    In 1976, 26.8 percent of voters lived in a landslide county. (Democratic landslide counties are in black; Republican landslides are gray.) In close elections, the percentage of voters living in landslide counties rose steadily. By 2004, 48.3 percent of voters lived in a county where the contest between George W. Bush and John Kerry wasn't close at all. About six of every 10 counties were won by landslide margins in '04.

    Obama is running against a man whose chief virtue seems to be that he withstood five years of arduous imprisonment and torture and, since he could not equal the Navy record of his father and grandfather, went into politics after he married a rich wife. McCain has changed his positions as the years have progressed, but he has always supported the super-rich through the years as our society has divided.

    A friend and former colleague of mine in the Foreign Service, Kevin McGuire, some time ago drafted a short statement of support for Obama and began to ask retired Foreign Service officers if they would sign it. So far 334 of us have done so, including by my count 66 former American ambassadors.

    If you would like to know why we have done so and who we are, you can find our reasons and our signatures at Foreign Policy for Obama.Com: Declaration of Support by Over 280 Former Diplomats. (Ed. note: the number is now over 330.)

    PS I’ve just found the reason the US dropped the Bomb on the Japanese not the Germans. It wasn’t ready until after Germany has surrendered. Eisenhower pleaded with Truman the US not to use it on Japan. And Kyoto was the favoured target but Stimson said no due to it’s architecture and culture (and Dresden criticism).

    Analysis of how Obama might win Georgia (if he does)

    [
    The big question is not if African-Americans' share of the electorate will increase, but by how much and what that will do to the share of the electorate made up by whites. The potential electorate could look as follows.

    Whites: 64 percent African Americans: 31 percent Hispanics: 5 percent

    Let's say McCain gets 71% of the white vote, Obama 26%, and [Third Party candidate] Bob Barr 3%, which is reasonable and perhaps a bit cautious on Obama’s and Barr’s shares. Then there is the Hispanic vote, which favored Bush in 2004 but nearly everyone has now given Obama roughly 2-1. Meanwhile, let’s put Obama’s support among African-Americans at 95%, which I think is reasonable.

    The end result — if one assumes the same number of voters that showed up four years ago (3,280,000) come to the polls next week — would be as follows:

    Obama would end up with 49.39 percent of the vote (approximately 1,610,000 votes) McCain would end up with 48.64 percent of the vote (approximately 1,590,050 votes)

    You’re very hard to please Adam!

    Eisenhower was in Germany at the time when Stimson got word that the nuclear test in NM was successful. He argued with Stimson and rang Truman to dissuade him.

    MacArthur wasn’t consulted and apparently said he disagreed with it later.

    I found this list of people who disagreed with it;

    Saw the most goddarn awful hour long piece on Obama on Hammity this afternoon. I should have kept flicking through the channels but just couldn’t pass this one.

    Hammity had reasons (dotpointed) on why no-one, including him, should be voting for Obama. He dragged up the Rev. Wright thing, some Arab bloke who gave money for his campaign years ago, ‘community organising’ (mad it sound like a dirty word) and lots more. It will be run for the next 9 days.

    Some other GOP insider said that a private mob would be running ads for a few days on ‘Joe the Plumber’ and at the end of this McCain’s would be leading in the polls. Also suggested that Rev. Wright thing be rehashed continuously.

    Juliem, what on earth breeds this type of Republican attitude in each election. The things I have read about McCain make my insides curdle – he is not white angel but is that ever brought up in the media over there. The Republicans seem to be a little like the Libs here – if anyone is against them they can only denigrate.

    AiC you are being a little disingenuous about John McCain’s second marriage. You fail to mention that he left his disabled first wife, Carol, for a woman barely older than his oldest son in 1980.

    Subsequently Cindy has proved to be a little bit of lead in his saddlebags given her addictions and theft of medications. Being white, blonde, and well connected she got a plea bargain on that little “incident”.
