I think that the electorate has stopped listening. All Barack Obama has to do is run a disciplined campaign from here on in and he will win - though he might want to muzzle the embarrassment that is his VP pick until after November 4.
You can see from the betting graph that Obama has a big lead, which has increased due to recent poor economic news. Opinion polls may tell one story but money always seems to be the strongest indicator of performance.
The irony is that voters will be electing the party that caused the mess in the first place.
