Probably a bit early for a 'Why Obama will win Reelection' thread, but he's looking good at the starting gates.
The guy is a pragmatist- not a left wing loonie, not a Chicago mobster, a Muslim, an Arab, or a race warrior. A moderate in every sense of the word- not a radical statist like Bush. The Press reports I am reading suggest a growing comfort level with his pending administration, even among many former sceptics.
One obvious factor that differentiates Obama from the myopic Bush administration is that he is casting his net much wider for his senior advisers- for example he has financial conservatives in his team, and is retaining Gates as Pentagon chief. Not just a bunch of neo-con relics like Bush' team, or Chicago politicians as was implied by a few here.
