“ President Elizabeth Warren” began trending on Twitter during the Democratic debate on Tuesday night, and CNN all but made it happen.

The liberal media is all-in for Warren, and that's been true for some time. But it was even more evident at the latest Democratic debate, during which moderators largely refrained from challenging Warren on her policy proposals, choosing instead to target her rival Bernie Sanders.

On Monday, CNN reported an apparent leak from the Warren campaign claiming that Sanders told the Massachusetts senator that a woman couldn't win the presidency. That set up Sanders vs. Warren as the showdown to watch on Tuesday, but CNN's moderators didn't even permit a fair fight.

After Sanders denied that he'd ever made the supposedly sexist comment, CNN debate moderator Abby Phillip asked for a response from Warren. Instead of referring to the comment as an allegation, Phillip said, "Sen. Warren, what did you think when Sen. Sanders told you a woman could not win the election?"

Warren delivered her reply, and Phillip concluded: "Sen. Warren, I want to give you the final word."

That could be a good summary of CNN's editorial ambitions. It's not interested in giving other candidates a fair hearing. CNN is all-in for Warren.
