(CNN) - Rick Perry's campaign wasted no time going after Rick Santorum following the release of a new CNN/Time/ORC International poll that showed the former Pennsylvania senator surging into third place in Iowa.
In a new radio ad released by Perry's team Thursday, Santorum is portrayed as a free-spending Washington insider who voted for earmarks and wasteful spending during his time in Congress.
The ad mimics a game show, asking questions of contestants like "Which Republican running for president voted for the bridge to nowhere?" and "Who personally demanded more that $1 billion in earmarks to his sixteen years in Congress?"
Each time the announcer proclaims the answer: "Rick Santorum!"
The spot features a clip of Santorum saying he was "very proud of the earmarks" he wrote into spending legislation.
"Rick Santorum is proud of feeding at the earmark trough in Congress," Perry's ad proclaims.
