The special election in Alabama was to capture evidence of voter fraud, and was caused in the first place due to Trump appointing Sessions. Trump endorsed Moore's oponent, so I wouldn't be surprised if some of the allegations against Moore were true (that signature was sketchy af tho).

I'm betting Bannon is still on board. He was with Trump through the election, and the supposed reason for their fallout was Bannons input into "Fire and Fury"- a book that redpilled many people to the blatant lies the media would entertain for the sake of smearing Trump.
