Like I said back in June even the Democrats can't support Obama. Now that the cracks have started to show on this empty suit the Democrats are having buyers remorse. There is a lot of speculation that Hillary is going to pull something at the convention. That isn't going to happen for a number of reasons and it suits her purposes to have Obama lose in November, so she can comeback in 2012 and vindicate herself and the Party.
Keep an eye out for the fireworks in Denver, but it will mostly be smoke and mirrors.
