Jonathan Chait, New York: “I can understand why somebody who never shared Obama’s goals would vote against his reelection. If you think the tax code already punishes the rich too heavily, that it’s not government’s role to subsidize health insurance for those who can’t obtain it, that the military shouldn’t have to let gays serve openly, and so on, then Obama’s presidency has been a disaster, but you probably didn’t vote for him last time. For anybody who voted for Obama in 2008 and had even the vaguest sense of his platform, the notion that he has fallen short of some plausible performance threshold seems to me unfathomable.”
