Keep an eye on one number...50%...a candidate who is at 50% going into the last weekend of the election rarely loses.
Now take that with a grain of salt, in 2000 GWB was at 50%, and the polls are all over the map, but look for across the board consistency of 50% in the majority of polls, especially watch IBD/TIPP.
I find it intresting that Obama has dropped below 50 in the RCP average. and that includes the MSM Obama bombs.
