Through these 26 states, Hillary has received 2.14 million fewer white votes in '16 than she did in '08. She's down in 23 states and up in just three.
Of those three, South Carolina and Illinois have easy explanations. In '08 North Carolina senator John Edwards won a plurality of the white vote. The primary occurred when there were still three electorally serious candidates in the race.
Obama had home field advantage in Illinois in '08. Even so, Hillary's white vote increase in '16 was still quite modest.
Virginia is the only state she convincingly improved her white support in from '08 to '16. Lots of federal government trough-feeding (defense) industries and contractors in the state who were afraid Sanders would cut their allotments?
In an attempt to put Sanders away, Hillary has said her top presidential priorities will be gun control and immigration 'reform'--amnesty, citizenship, etc. Trump, in contrast, has made immigration his signature issue and recently received the NRA's endorsement.
While Black Lives Matter becomes increasingly brazen and thuggish, Hillary is singing paeans for Trayvon Martin's reckless, derelict mother. Trump unapologetically points out that the group is trash.
From her failed run in '08 Hillary learned that winning white Democrats over doesn't matter. White Democrats won't convincingly support a candidate blacks don't. Blacks, in contrast, are monolithic and all vote for the same person. Ergo, white voters can go to hell, both in the primaries and in the general election.
This election is shaping up to be one of the most lopsided in history among whites. Given that Trump will need nearly two-thirds of the white vote to win, it can't be lopsided enough.
