"An Honest Socialist/Could Bernie Sanders show Elizabeth Warren how to beat Hillary?"

A Wall Street Journal editorial. (There's a subscription wall that you can bypass if you Google some of the text and get your own link.)

Milton Friedman once observed that the 1928 platform of the Socialist Party of America may have seemed radical at the time, but nearly all of it was eventually absorbed by mainstream parties and became law. That�s also Mr. Sanders�s hope. He wants to drive the Democratic Party debate to the left so it drags Hillary Clinton along with it.

And it may be working. Mrs. Clinton has already disavowed her husband�s trade agenda. She�s proposed a rewrite of the First Amendment to limit political speech, and don�t be surprised if she also embraces expanded entitlements. The difference is that Bernie believes what he says, while Hillary believes whatever seems necessary to win.

The practical political question is whether Mr. Sanders, or some other liberal gadfly, can do well enough to serve as a stalking horse for a stronger candidate against Mrs. Clinton. Recall how Eugene McCarthy drove LBJ out of the 1968 race with a strong performance in the New Hampshire primary. Robert Kennedy soon jumped in as a more electable antiwar candidate.

LBJ really was someone who would say whatever was necessary to win. As for that 1968 business... we ended up with Nixon... who by today's standards was a big old liberal.

[NOTE: The last paragraph of this post is rewritten. Originally, it said: "And we ended up with LBJ, who really was someone who would say whatever was necessary to win." That's not a proper account of 1968!]
