Blue-Collar Whites Are Leaving Trump
This doesn't matter much, and I'll tell you why. They are not leaving Trump because they are moving leftward ideologically, or returning back to their union-inspired roots in the Democratic party. The opposite. They are disappointed that he hasn't been as racist and backwards as he promised to be. Where's that damned wall?
So his approval rating is declining within the group because he hasn't fulfilled some of his promises. Big deal. On election day, given the choice between Trump and somebody they consider to be a liberal commie pantywaist, they are not going to vote for friggin' Pocahontas or anybody else condemned by Fox News as an obvious descendant of Karl Marx. The angry whites are goin' for Trump, as ordered by Sean Hannity and Rush Limbaugh and their crackpottier cohorts.
If the Dems are gonna beat this Trump dude, they're going to have to erode his base among educated white voters, while making sure that their own natural constituency (millennials, minorities, and of course commie pantywaists) makes its way to the voting booths.
