That's more of the progressive contingent still playing to what is amounting to a small segment of their base and still not realizing they are alienating a good percentage of what should be their base. The simple fact that most of the union bosses are giving Trump at least some props should be a wake up call to dems. Not sure how I feel about union love for Trump, but the fact that he's getting it means he's saying something all those working class dems want to hear.
This is where Trump or an advisor is playing some clever politics. The Dem's have moved to the left. Trump has used the vacuum to claim the white working class and union voters who have traditionally voted Democrat. They have to oppose Trump on any immigration because they need to import more Democrats.
If Trump succeeds in just about any of his proposals, the Dem's will lose the working class and union voters. So they need to stop Trump, no matter how much doing so may harm the country. They will stonewall him on his proposal for child care, on his proposed agreement with Trudeau to help women start their own companies, on his proposals for rebuilding the inner cities, etc. The feminists and the race hustlers will double-cross their own people to help the Democrats stop Trump.
I really think that, if Trump proposed giving amnesty to illegals already here, the Dem's would oppose any of that legislation.
