There Should Be Blood

"The truly undecided voter is rare, say those who study the psychology of voting," Joe Garofoli wrote in The San Francisco Chronicle. "Since neuroscientists say 90 percent of thought is unconscious, an undecided voter may have already decided--he just hasn't revealed his pick to himself yet."

Whether I'm a rare bird or a typical victim of self-denial, I didn't know how I was going to vote until election day--or, to be more precise, a election minute. Roughly 15 to 20 percent of 2008 primary voters have had similar trouble getting their unconscious to talk to them.
