The Karl Rove-backed group American Crossroads has come out with an ad that links Elizabeth Warren with the Occupy Wall Street movement. The open disdain is about as a subtle as a punch in the face.

NARRATOR: At Occupy Wall Street, protesters attack police, do drugs, and trash public parks. They support radical redistribution of wealth and violence. But Warren boasts "I created much of the intellectual foundation for what they do. I support what they do."

And so on.

The Boston Globe reports they'll spend $596,000 to air it, which sounds like a lot but really isn't in the expensive Boston market, and is just the first salvo from them against "Professor" Warren. This is just testing the waters now to see if it has any resonance with voters later on. That they're airing it this early though tells you everything you need to know about just how worried they are already.

UPDATE: (Editor's Note: Please send donations to Blue America's act blue page for Elizabeth Warren so she has a chance to fight back against these vicious Rovian smears)
