I think Democrats will come home in the North and West and that Republicans will come home in the South and farm states and that it will be a lot like last time. Then again, there could be a landslide if one base comes home and another doesn't.
They could come home in some/most states, but not everywhere. The map does slowly change over time, and we shouldn't expect everything to line up the same as 2012. And of course, Clinton isn't Obama, so she'll inevitably be stronger in some states than he was, and weaker in others. (Likewise, Christie isn't Romney.)
