A single poll is not going to tell you who is going to win the election, but does provide a picture of how the race is going at that point in time. This information is valuable to candidates and helps to guide their campaigns. Polling data is quite worthy of discussion, and should not be eschewed simply because the #'s will change constantly before November.

To say polling data is meaningless is like saying 97% of a football game is meaningless because any team has the possibility of winning the game in the last two minutes.
