"SHAME ON YOU, BARACK OBAMA": Romney Uses Hillary Clinton In Colorado TV Ad

Mitt Romney's campaign quietly released a new TV ad that's running here in Colorado. It uses Hillary Clinton to bash Obama for lying about Romney's record.

It's a timely ad since Obama was called out as a liar by the Supreme Court yesterday for denying Obamacare was a tax.

The ad is also running in Iowa, Virginia, North Carolina, New Hampshire and Nevada.
