Fox News polls have always had a Dem bias. They outright predicted a Kerry victory! So your little act of pretending like Fox produced GOP friendly polling is disingenuous.
46-46 is devastating for an incumbent 1 week out.
Even if the Fox poll wasn’t skewed, a 46-46 tie usually translates into a 52-48 victory for the challenger as the undecided usually break to the challenger by a huge margin. Given the sampling bias, and the fact that we have overwhelmingly won every single election (from Mass to NJ to the 2010 midterm, to Scott Walker) that has been held since Obama took office, I am very optimistic about this election.
