I just don't understand. I really don't.
Like Bill Clinton said at the DNC, unless people are "feeling it", they vote you out and we've all learned that people vote their pocketbooks. If you were unemployed four years ago and you're unemployed today, or you took a lesser job to survive and/or you got unemployed during the last four years, you're looking for any reason to vote the incumbent out. Some things don't change.
Well, sure, the economy's not great. I just don't understand how a debate where nothing particularly noteworthy happened—no gaffes, no witty one-liners—has led to a
four point change in the polls in a year where until now the polls had basically been the most static of any presidential election year since the beginning of polling.
