Boss Steve Bannon, former Trump guru exiled to relative obscurity in the white nationalist Breitbart Mafia he created, has put out a contract on the Republican party.

According to Politico:

President Donald Trump’s closest allies are planning a slate of primary challenges against Republican senators, potentially undermining the party’s prospects in 2018 and further inflaming tensions between GOP leaders and the White House.

The effort is being led by Steve Bannon, Trump’s bomb-throwing former chief strategist, who is launching an all-out war against Senate Majority Leader Mitch McConnell and the Republican establishment. Bannon has begun holding private meetings with insurgent challengers, vowing his support. He’s coordinating with conservative mega-donor Robert Mercer, who is prepared to pour millions of dollars into attacks on GOP incumbents. Bannon has also installed a confidant at an outside group that is expected to target Republican lawmakers and push the Trump agenda.

This, as you might imagine, has the alarm bills clanging at the Republican National Committee and among the senior Republicans in Congress who fret over whether the hit ordered by Bannon will drain millions of dollars from the parties bank accounts, money they need to take on Democrats in the general election.

Boss Bannon’s anti-incumbent effort could reshape the entire 2018 primary landscape, if Bannon follows through. This would pit a group of pro Trump primary challengers against sitting legislators who are perceived as more mainstream. In addition to Sen. Mitch McConnell, the Senate majority leader, and Jeff Flake, senator from Arizona, Boss Baonnon also looks to push buttons on Tennessee Sen. Bob Corker and Mississippi Sen. Roger Wicker. Bannon also seems prepared to put the Breitbart Mob’s money on the street to support the candidacy of former Alabama Supreme Court Chief Justice Roy Moore. McConnell had gone all in for Sen. Luther Strange, who was appointed earlier this year to fill the seat after Jeff sessions became attorney general.
