The Trump Democrats
The unions see the solution as pushing for liberalism within the GOP. Many of Trump's policies appear to be consistent with that objective.
Many conservatives and Republicans alike have been baffled as to how Donald Trump, a guy who opposes everything most conservatives and Republicans believe in, could beat out base pleasers like Ted Cruz, in solid Republican states.
It's crossover Democrats doing this, and now even the unions are starting to worry that it'll cost Hillary Clinton the election.
I got a great deal of pushback when I first mooted the theory. It fit the pattern: the policies, the rhetoric, and the turnout figures all pointed to outsiders coming into the party. Further, the climate in the Democrat party has shifted. Black Lives Matter broke through the usual 'race' quarantining the Democrats do, thanks to the Voting Rights Act's Majority-Minority districting.
National Democrats usually only talk about issues relevant to black voters in black churches. That's why they go there and why the press never covers it. If the Trump Democrats had heard this stuff years ago, they'd have revolted. But Black Lives Matter protestors forced Hillary Clinton and Bernie Sanders to affirm support for them publicly, outside of the safe confines of a black church with no cameras rolling. So, the last remnants of the Robert C. Byrd/Ku Klux Klan wing of the Democrats, bolted.
They're Trump voters now. They are the Trump Democrats. If allowed to take over the GOP they'd ruin that party for conservatives. These are folks who could be relied upon to vote for people like Jimmy Carter and Bill Clinton, but now they're going to vote for Donald Trump. The unions are worried, but they have a solution.
