Republicans cannot win nationally while winning Indiana by less than 10%.
Why ? it's a 9 % shift compared to 2008. Enough to win at national level.
This is a more 'normal' year in Indiana in the Presidential race because the D nominee has spent little time there and has not built or maintained a political apparatus. A 9% shift nationwide would win for Romney. Romney winning the state by only 9% is consistent with R losses in 1960, 1976, 1992, and 1996 when the Democrat didn't have early media penetration, had no connections to the state, and made few appearnaces.
