It's a bit weird that WI is tighter than VA. Were the polls both done over the same three days?
Could be that Wisconsin is simply more "elastic" than Virginia. You know, having more white people and all.
This is correct, but it is way too simplistic to just say "white people" and be done with it. Virginia has a lot of southern whites who are voting for Romney no matter what and liberals up in NOVA who are voting for Obama no matter what. Add in a bunch of Blacks and Puerto Ricans and you have a fairly stable electorate. In Wisconsin you have the northern half of the state being working class whites living in small, but industrial, towns with no racial tension. These are quintessential swing voters.
