If you're looking for political information from outside the current administration, you can check out PolitiFact. It's kind of like Snopes for recent US politics. It tracks the truthiness of politicans' claims, whether they flip on issues (which I don't necessarily have a problem with- there's nothing wrong with changing your mind based on new information), and there's a special tracker for all of Obama's campaign promises. For only being on the job for two weeks, he's off to a pretty good start.
