There is a context to the Republican moves in Michigan to pass a right to work law.
When you see increasing levels of rejection by the electorate, along with an increasingly radical and delusional base pushing in the other direction, your only alternative is to direct your actions toward political advantage by things like Gerrymandering, and going after your opponents’ power base, and you dry to prevent them from voting.
That’s why you see Republicans going after labor unions, plaintiff’s lawyers, and actively suppressing voter turnout.
Well, there’s that, there’s the fact that they, as Lee Atwater said, scream N***er, N***er, N***er, albeit with increasingly sophisticated code words.
If this passes, and it almost certainly will, then when the Democrats get power back in Michigan, repealing this is the first order of business.
