Unfortunately, most of the deplorables would just find new reasons to hate Democrats, because their party preference is rooted in tribalism rather than in policy, and you'd scare off lots of lefties who don't think the state should be outlawing important medical procedures.

That is objectively false - Trump won because white voters in the rust belt swung 25 points from Obama to Trump. If you were right that they voted only Republican out of tribalism then Obama would never have won those states.
Why not? Trump didn't win them by much, but it can still be a big swing if Obama won these states by a lot. A quick google shows that this appears to be the case.
Trump may have won michigan by only 10k votes, but Obama had a margin of half a million in 2012.
