Another example of how institutional interests create friction between congressional Republicans and Trump.
Out of personal pique, he is willing to put a marginal GOP Senate seat at risk. Alex Isenstadt reports at Politico:
The White House has met with at least three actual or prospective primary challengers to Arizona Sen. Jeff Flake in recent weeks, a reflection of Donald Trump’s strained relations with the senator and the latest sign of the president’s willingness to play hardball with lawmakers who cross him — even Republican incumbents.
Flake, a longtime Trump critic who refused to endorse the president during the 2016 campaign, is one of a handful of undecided Republican votes on the Obamacare repeal effort. He’s also one of the most vulnerable Republicans up for reelection in 2018.
