Well each yank state has own elections, so not really national election per say.
If I recall didnt all the polls say that Kerry was going to win 4yrs ago? Who actually won????
Polls are worthless - sample of 1000 people. This can't be projected for the entire country - too many variables.
I think you will see many people saying they will vote for Osama, but when it comes down to it - they won't do it.
