Todd-Ambinder August analysis:
Probably the best way to describe this campaign right now is that Clinton is going 75 mph; Obama is going 50 and has plenty of gas to spare. Obama looks like he can eventually go faster in his campaign car, but he's not doing it yet.
Obama will make his move in the late fall. This is a 1500 meters run. We're at the first lap and it's fine for Clinton to stay in the lead for a while.
