Danny Tarkanian, apparently at the urging of the President, has ended his primary challenge to Heller and is running for House district 3 instead. He narrowly lost district 3 in 2016, while Trump narrowly carried the district. Several other prominent Republicans appear to be running, the seat is open as freshman rat Jackie Rosen is running for Senate.
Heller has a few other primary challengers, all desultory, so he’s as good as renominated, with the support of the President.
The bad news is that Baris thinks he can’t win, that he’s polling at 30% cuz of his neverTrumpism.
