This (slightly bizarre) chart shows how the GOP’s current era of good feeling is headed for a blow up in Arizona. The three main candidates in the Republican primary for Jeff Flake’s Senate seat have already been tacitly or directly endorsed by the three poles of the Republican party: Kelli Ward secured Steve Bannon’s endorsement back when that meant something, Donald Trump pardoned Joe Arpaio and Mitch McConnell has dropped not-so-subtle hints that he’d like to see Martha McSally be the Republican nominee. Assuming that Ward is as dead in the water as Bannon’s political career appears to be, it leaves Trump and McConnell on  opposite sides of a primary, and there are national implications to either of them switching sides in order: Trump turning his back on Arpaio  would mean abandoning someone who he’s already invested quite a bit of political capital (looks weak!) while McConnell would be saddling the national GOP brand with one of the most virulent anti-immigrant figures around at a time when all the happy talk in D.C. is about comprehensive immigration reform. The primary is not until August 28, so enjoy the next seven months!
