Former Minnesota Gov. Tim Pawlenty and businessman Herman Cain (R) have landed a big-name performer for their Ames Straw Poll tents: former Arkansas Gov. Mike Huckabee (R).

Huckabee, whose political action committee HuckPAC will have a booth at the poll, will perform with boh candidates.

Sarah Huckabee Sanders, who ran her father's Iowa field operation in 2007 and 2008, is doing the same for Pawlenty this cycle. Sanders tweeted that she was "very excited" that Huckabee would perform with the campaign.

"Gov. Huckabee will be playing bass and Mr. Huckabee will be singing," Cain Communications Director Ellen Carmichael told The Hill. "The governor and Mr. Cain are going to collaborate on the arrangement. We're still waiting to hear what they decide on."

Huckabee's second-place finish in the Ames Straw Poll four years ago helped establish him as a serious contender in the state, and he won the GOP caucuses there months later. He is popular with evangelical conservatives in the state and has thus far not gotten involved with the Republican field for 2012. 

Pawlenty has a strong field organization in Iowa and Cain has a strong Tea Party following but both have been overshadowed in the state by Rep. Michele Bachmann (R-Minn.), and have so far failed to gained traction in polls.

Carmichael played it coy when asked if the duet could lead to an endorsement. "We'll see what Gov. Huckabee decides," she said.
