Meghan McCain, the daughter of Arizona's senior senator John McCain, had three simple words for Breitbart News' Steve Bannon after Democrat Doug Jones defeated Bannon's favored candidate, Republican Roy Moore, in Tuesday's special election for Alabama's open Senate seat. 

"Suck it, Bannon," McCain tweeted Tuesday night. 

Bannon passionately campaigned for Moore, and after allegations of sexual misconduct against the Alabama Republican surfaced, he campaigned ever harder. He savaged Republicans like Senator Majority Leader Mitch McConnell and Mitt Romney who called for Moore to drop out of the race in the wake of the allegations. 

Bannon is trying to lead a populist insurgency within the Republican party and has declared a "season of war" against what he considers the "GOP establishment" — in which he includes Meghan McCain's father.
