Breitbart Worked with Democrat Operative to Sabotage GOP Primary

Why would Black, a committed Democrat, work with a supposedly conservative publication to affect Republican primary results?

As hacked WikiLeaks emails from the Clinton campaign recently revealed, the Clinton campaign feared going up against Rubio in the general election.

Rubio may have actually won, an outcome which neither Black nor Breitbart desired. Put another way, Breitbart was willing to chance Hillary Clinton becoming president rather than see Marco Rubio beat her. This obliterates the already fallacious argument advanced by Breitbart that the "never Trump" contingent supports Hillary Clinton. They don't get to toss that accusation around after actively working with Democrats to sabotage Republicans who could have beat her.
