The way out of the worst of this is obvious: Congressional Republicans need to use their leverage to insist the president hire a real chief of staff to clean house — including removing Bannon — and run the administration properly. Unfortunately, we haven't seen any hint of it so far. Instead of floating names such as Rob Portman, Mitch Daniels or Lamar Alexander, some Republicans are apparently trying to rally around Priebus, who may not be as objectionable as Bannon but doesn't have the capacity to get the administration on track. If the Russia scandal is, as NBC's First Read said Wednesday, "arguably the biggest scandal involving a foreign government since Iran-Contra," then the solution is the same as it was then: Investigate the scandal to be sure, but meanwhile get a steady hand in the White House to make up for the president's shortcomings.
