one thing to look at for the election is voter turn out
lets face it, most americans most years don't vote
however the dems have been very motivated during the primaries and they're turning out in record numbers for primaries
the dems could turn a lot of those historically red states just by having a larger % of the party turning out to vote
i know the republicans don't have much of a fight going on, but the dems are turning out massive numbers compared to the republicans
if the dems can stay motivated you might see a whole new map this year
