I went back to answer my own question about how Bannon and Trump got together in the first place:

In 2011, as Mr. Trump pondered a 2012 presidential run, David Bossie, a conservative activist who headed Citizens United, took Mr. Bannon to Trump Tower in New York to meet him. “They definitely hit it off,” said Mr. Bossie

Ah, David Bossie (Trump Deputy Campaign manager), Citizens United stooge and long-time Clinton hater/conspiracy hack, who originally rose to prominence as Dan Burton’s “investigator” of all things Clinton. Even before that, Bossie worked with Floyd Brown, the guy who created the Willie Horton ad. Willie Horton ad.

Excuse me, I need to go take a shower.
