Obama beat McCain by 1% in 2008. If Romney beats Obama by 16% in 2012, and the trend goes across the board, Obama could be in for a real wipeout.
I do like the “rising tide lifts all boats” theory (or at least the suggestion that a tide in one place is at least an indicator elsewhere), but out of curiosity, since I’m not from there, has any part of Indiana been more adversely affected than the rest of the country to account for such a huge swing there?
