This is the first election mailer I’ve received this year. There are three possible explanations I can think of for this mailer, apparently sent out to all GOP primary voters in MI.

1. They want to help the GOP in the state and Federal House elections. Healthcare is always a winning issue for Republicans everywhere. The GOP revolutions of 1994 and 2010, both of which resulted in massive GOP gains in the House and in state legislatures, can both be directly attributable to popular anger over unpopular Dem-backed health care reforms.
2. They have a budget, and this feels like the sort of stuff they should be doing to keep their jobs. They don’t expect it to have any real effect.
3. They think Michigan can become a swing state. This is hardly impossible, as Trump will certainly do better in MI than Mitt, as well as win more counties. MI is slightly less reachable than PA, I think, but not by much.

In any case, it shows local GOPes are hardly abandoning the presidential race at this point, even in blue-ish states like MI.
