Couldn't agree more:
Obama is no (in the 1970s sense) "liberal": There are many who are upset by this who believe this (and other recent moves) shows Obama "moving to the center." People who make this argument signal they don't know squat about which they speak. You can't read Obama's books, watch how he behaved in the Illinois Senate, and watched how he voted in the US Senate, and believe he is a Bernie Sanders liberal. He is not now, and nor has ever been. That's not to say there aren't issues on which he takes a liberal position. It is to say that the mix of views he actually has and has had doesn't map on a 1970s spectrum of liberals to conservative.
The right doesn't know what to make of Obama because he has transcended their Rovian categories. So he either has to be a radical like McGovern or a hollow opportunist like Clinton. He is, in fact, neither. And while the old school left and right bicker over him, my sense is that many others are slowly getting his message.
