The 2004 October Surprise, and What It Means for 2012

I’m generally not a big believe in “October surprises,” which seem to be more numerous in folklore than fact.  But this guest post by Michael Tesler made me stop and think.

John Kerry believed he would have been the 44th president of the United States had it not been for the surprise surfacing of a new Osama bin Laden videotape the Friday before the 2004 election (October 29).  This was one of the few points of agreement between Kerry and George W. Bush, who also acknowledged that the bin Laden video helped him win reelection.

Osama’s October Surprise could have bolstered Bush by making his popular war on terror performance (60 percent issue approval ratings in fall 2004 Gallup polls) more prominent in Americans’ vote choices.  Indeed, research on priming suggests that renewed attention to a particular issue like terrorism can make related considerations more important in subsequent political evaluations (though see here for an alternative account).  Kerry Campaign strategist, Bob Shrum, suggested that the bin Laden tape had such an effect.  Or as he put it in his 2007 autobiography, “We had fought for months to keep the contest from simply being a 9/11 election.  [After the OBL video] that’s what it would become.”  Shrum’s 2004 Republican counterpart, Ken Mehlman, concurred, stating, “It reinforced an issue on which Bush had a big lead over Kerry.”

There is some empirical evidence to support those contentions too.  The figure below draws on data from the National Annenberg Election Study to examine the relationship between Bush’s war on terror approval and Americans’ vote intentions immediately before and after the bin Laden tape was released.  After controlling for respondents’ evaluations of Bush’s performance on Iraq and the economy—two issues where the president was underwater leading up to his reelection—the display indicates that Americans’ assessments of the president’s war on terror performance were significantly stronger predictors of vote choices in the final three days of the campaign than they had been right before the video broke.  Meanwhile, the public’s more negative opinions about Bush’s Iraq and economic performance decreased in importance during that time period.

To be sure, changing opinions about how Bush was handling the war on terror in the aftermath of the video’s release could be responsible for some of the enhanced relationship shown above.  There are a couple of reasons to suspect that this was not the case, though.  First, Bush’s war on terror approval rating was virtually unchanged among Democrats and Republicans before and after the video.  Second, Gabriel Lenz’s outstanding new book convincingly shows that performance evaluations are typically primed, rather than changed, by presidential campaigns.

If October surprises can, in fact, activate relevant performance evaluations in the final week of a presidential campaign then Hurricane Sandy may well be a boon to Obama’s reelection prospects.  After all, one of the presidents’ biggest issue advantage (52 to 40 percent) over Romney in an October 10-13, 2012 ABC/Washington Post Poll was on the question of “who do you trust to do a better job handling an unsuspected major crisis.”
