I am going to guess McCain, but that is only considering the jump republicans typically get compared to the polls.

As far as the polls are concerned, there have been multiple reports from a few different polling agencies that say that the polling is done in a way that will always slant democrat. IE: polling in low income areas or other heavily democrat areas. Another report pointed out inaccuracy of exit polling where 75% of dems will take the poll, while only 40% of repubs do.

Lastly, with regards to "funny" happenings with the ballots. I think the dems have a lock on that subject this year. There is WIDESPREAD voter fraud taking place in support of Obama. My own little story on the subject. I was out at subway on Thorton Rd. and I=20 a few weeks ago, right before the deadline, and there was someone there doing voter registration. He was actually wearing an Obama button, and a Obama bumper sticker on a hat. The guy walked right past me and right to the lady wearing an Obama sticker and asked her if she was registered to vote. If he was so interested in just registereing poeple to vote, why not ask me and my wife also?
