Well, lots of questions will be answered on election day. But, this campaign season has seen so many polls which seem to be doctored, to make it seem that Obama is more popular than he really is. Nov. 6th will reveal the truth.
Rasmussen seems to me to be hedging a little conservative (in terms of numbers, not politics) during the Romney surge. It's unlike the usual landscape to have many other polls moving in favor of the Republicans as much or more than Rasmussen. It's unusual for my own assessment to be 3 points greater than Rasmussen's.
