The Washington Post’s Greg Sargent writes that former White House chief strategist and current Breitbart Executive Chairman Steve Bannon is “is planning to escalate his war with the GOP establishment, by promoting primary challengers who will run against GOP incumbents on a platform that is fully faithful” to the populist and economic nationalist issues that got President Trump elected in 2016.

From the Washington Post:

Bannon has privately argued that the Sept. 26 runoff between Moore and Strange is (in the words of Politico) a “defining battle between the conservative base and GOP establishment” and that defeating Strange would “open the floodgates” to more Trumpist candidates to challenge Republicans in other primaries.

But here’s the question: What will these Trumpist challengers actually run on? Obviously one possibility is that they will campaign on things we know Bannon (and Trump) support, such as more protectionist trade deals; tighter restrictions on legal immigration; a demand that congressional Republicans fund Trump’s wall on the southern border; and a deportation dragnet that is expanded well beyond its current reach under Trump.

Indeed, Bannon provided an important clue along these lines in an interview with Charlie Rose, in which Bannon criticized the handling of the “dreamers” by Republicans and Trump as too soft. Trump has canceled protections for hundreds of thousands of people brought here illegally as children, which will drive them out of jobs and possibly subject them to deportation. Republicans are talking about a legislative solution for the dreamers, and Trump has hinted at openness to signing such a measure, or if one does not materialize, to renewing executive protections for them.
