Bayh would certainly carry Indiana because in America, we still do elect people and not parties.
Actually this is only partially true - it is the case in some states but not all. Indiana is a good example of a state that could vote for a personality - for example a DINO - in spite of being a very strong GOP state. I agree here.
However the South will no longer vote for a Democrat for president due to religion and racism - the Democrats are perceived as favoring the blacks and and not obeying christian rule. Conversely, the Northeast will not vote GOP, regardless of the individual running for fear of further empowering the religious fanatics.
I very much disagree here. Clinton carried quite a few states in the South, and probably still would today. Dems continue to win a lot of races at the state level in most parts of the South, and the same goes for Reps in the NE.
Really the only regions lost to "voting for personalities" are the exurbs and maybe the inner cities. And that's more to do with the psychological impact of not living in a neighborhood than with the parties...people will cling to their party as a neighborhood replacement.
That's why that racist who upstaged the Reps in the TN-08 primary, was nominated on their ticket, got totally bombed in the rural parts of the district but did decently in the suburbs.
