Polls VS Election

I don't know why they, (Whoever 'THEY' are?!') keep putting all 'thier' money on the Polls in the USA. There have been instances of the polls being wrong.
(POLL = Asking a number of people whom or what they would choose when given a choice.) Nobody asked ME yet! I'll just go ahead and tell them tomorrow.
(Election Day in the U.S.) So far, Republicans lead. (Acording to those same polls.) The final results aren't in yet. We'll see!
