WELL, TO BE FAIR, IT’S NOT AS IF SHE CAN RUN ON HER RECORD: Clinton allies shout ‘sexism’ at Sanders.

The once respectful Democratic primary has devolved into a slugfest about gender, with Hillary Clinton surrogates expressing outrage over how Bernie Sanders is conducting his campaign — even calling for him to fire his staff over alleged sexist remarks.

The ugly dispute has knocked Sanders back on his heels, and placed him on the defensive — an unaccustomed position for a progressive who describes himself as a feminist. And it’s sent a signal flare to Republicans, who have been reminded of the pitfalls of using the wrong language when taking on Clinton — and also of her campaign’s ability to turn it to her advantage.

Meh. Anybody who’s a threat to Hillary will be called sexist. My advice to Bernie is to respond that . . . this is what you get from a failed establishment politician who can’t run on her record. Because, you know, it is.
