Poll was still run during the convention so numbers are not going to show true "reflection" of voters thoughts on Kerry. Watch the numbers this week. Early after convention polls are showing Kerry losing support (up to 5 percentage points in some polls) and I think it will show a worse drop after the weekend. Also this isn't the worse Kerry will see, wait to the drop he experiences after the 1st debate!
I agree that after the debated both Presidential and VP.. that will be the true indicator. If the DNC was any preview of what Kerry and Edwards are going to be like in a debate. It is going to be a blood bath, and landslide for the GOP.(At least I hope so.)
