"this is going to let team Red claim to be the pro-worker team"

Nobody sane will believe them; while I believe the start of this was when the New Left captured "Team Blue" in the 1970s and blue collar workers famously became part of the Reagan coalition (and worked with him against the Soviet Union, particularly in Poland), the GOP establishment hates this part of its base.

Repeating part of another comment which in general is a repeat of all of this:

A great deal of Trump's otherwise inexplicable popularity is that he's a 1970s NYC Democrat just like Reagan in the 1980s was a self-described FDR Democrat and he doesn't hate these people. Doesn't care or do much for them, but this is a palpable difference from the GOPe.
