President Obama campaigned yesterday in Virginia for Democrat Terry McAuliffe, whose election in the governor's race is Tuesday. Obama praised McAuliffe's wife, their "unbelievable children," and McAuliffe himself.

"[H]e knows what it’s like to work hard," Obama said of McAuliffe. "And when it comes to creating good jobs, when it comes to investing in education, when it comes to giving more Virginians the opportunities that they deserve, Terry understands what folks are going through. He knows how to get things done. And that’s why I hope you guys are fired up, because we cannot have people stay at home when so much is at stake. I hope you’re ready to fight for Terry, because he’s ready to fight for you for the next four years."

Obama also mentioned a host of policies the two agree on ... but left his signature legislation off the laundry list. That is, Obama did not praise McAuliffe for his support of Obamacare. He did not mention Obamacare at all.

This, despite the fact that Obamacare is now a central issue in the Virginia gubernatorial campaign. The height of the campaign has come during the roll-out of Obamacare, which has been disastrous.

The president's silence suggests that even Obama realizes McAuliffe's support for the overhaul of the heath care system will hurt him.
