Disagree goldstategop, this reminds me of Election 2000, to me neither guy has a solid constituency outside of their normal base.
McCain has the edge IMO due to crossover Democrats (PUMA’s and others) and Undecideds braking to McCain.
IMO, we lost every close race in 2006 by about 1%-3%, this time around, McCain wins the close ones via the PUMA’s and Undecideds.
McCain owes a lot to the PUMA’s and independants, they will be the ones to put him over.
