Former Minnesota Gov. Tim Pawlenty (R) launched a second television ad on Tuesday highlighting his conservative accomplishments as governor.


A new 30-second TV ad boasts that Pawlenty "refused to cave in to government unions" during a 2004 transit strike, and that he "would not accept Democrats' massive tax and spending demands" amid a short-lived government shutdown in Minnesota in 2005.

The ad will go on the air statewide on Tuesday in Iowa, but Pawlenty's campaign had no immediate details about the money behind the ad buy. The spot is the second Pawlenty has put on the air in the caucus state; he launched a spot in late June shortly after a poll went into the field.

That poll showed Pawlenty earning support from just 4 percent of likely Republican caucus-goers, a somewhat disappointing figure given the intense efforts he's made in the state. His campaign reported raising $4.2 million between April and June, also a relatively low figure. 

The TV ad, Pawlenty's hoping, will help him build momentum in a state where he's staked a great deal of his campaign, and blunt the enthusiasm right now for candidates like Rep. Michele BachmannMichele Marie BachmannKlobuchar urges CNN town hall audience: 'That's when you guys are supposed to cheer, OK?'

Rick Perry (R).
