The CNN poll over-sampled Dems by 11 points. In 2008, Dems turn-out was +8 over Republicans. This can only mean that either CNN is consciously over sampling Dems, or that they believe the Dem turn-out tomorrow will be even higher than 2008 (every unlikely). And if CNN had to grossly over sample Dems in order to get a tie, how bad will Obama get beat when he has to face the music tomorrow? Mitt will win tomorrow in a near landslide victory. His coat-tails will propel a net gain of 7 seats in the Senate and 8-12 in the House.
