"Hours after the polls closed, your exit poll results for VA Senate race changed.

Webb did have 56% among women, and an overall lead based on the distribution.

ie 51% multiplied by 56 + 49% multiplied by what his percentage for males was gave a total of about 51% for Webb.

How is it possible for exit polls to change hours after the polls closed?

I'm remembering how the exit polls all flipped, or was it the final results that flipped suddenly in 04 courtesy of Diebold, Ken Blackwell, etc?"
