Crossroads GPS casts Obama speech as liberal in new ad

President Barack Obama proved during his inauguration speech Monday that he's a liberal, Crossroads GPS has argued in a new ad released Tuesday.

The conservative super PAC, which is linked to former George W. Bush strategist Karl Rove, featured in its ad "mainstream media" including ABC News/Yahoo News describing the president's speech as liberal. "I think you'll have a lot of them saying, 'Finally the president is laying out his real agenda, and guess what? He's a liberal,'" ABC News' Rick Klein is quoted saying in the commercial.

"If the media is calling Obama's policies liberal, what can we expect in the next four years?" the group asked in the ad.
