Conservative super PAC American Crossroads has a new ad running in Arkansas calling Democratic senator Mark Pryor a “rubber stamp” for Barack Obama.

“Mark Pryor has voted with Barack Obama at least 90 percent of the time,” says the voiceover in the 30-second spot. “For the failed stimulus, for higher taxes, more spending, trillions more in debt, and more job-killing regulations. And Pryor cast the deciding vote for Obamacare.”
