http://www.newsweek.com/id/107601 It is a core tenet of political psychology that voters know nothing. Or next to nothing. Or next to nothing about what civics classes (forgive the anachronism) told us really matters. In 1992, the one fact that almost every voter knew about George H. W. Bush, besides that he was the incumbent president, was that he loathed broccoli. A close second was the name of the Bushes' springer spaniel, Millie, which 86 percent of likely voters said they knew. But when it came to the positions of Bush and his opponent, Bill Clinton, on important issues, voters were, shall we say, a tad underinformed. Just 15 percent, for instance, knew that both candidates supported the death penalty.
The fact that people have what is euphemistically called cognitive-processing limitations—most cannot or will not learn about and remember candidates' records or positions—means voters must substitute something else for that missing knowledge. What that something is has become a heated topic among scientists who study decision-making, and, of course, campaign strategists and pollsters. Some answers are clear, however. In general elections, a large fraction of voters use political party as that substitute, says psychologist Drew Westen of Emory University; some 60 percent typically choose a candidate solely or largely by party affiliation. The next criterion is candidates' positions on issues; single-issue voters in particular will never even consider a candidate they disagree with. In a primary, however, party affiliation is no help, since all of the choices belong to the same one. And parsing positions doesn't help much this year, especially in the Democratic race, where the policy differences between Hillary Clinton and Barack Obama are minute. "When voting your party doesn't apply, and when the candidates don't differ much on the issues, you have to choose on some other basis," says political scientist Richard Lau of Rutgers University, coauthor of the 2006 book "How Voters Decide." "That's when you get people voting by heuristics
and going with their gut, with who they most identify with, or with how the candidates make them feel." What has emerged from the volatile and unpredictable primary season so far is that the candidates who can make voters feel enthusiasm and empathy—and, perhaps paradoxically, anxiety—are going to make it to November and maybe beyond.
