Minnesota Gov. Tim Pawlenty (R) made good Wednesday on his pledge to promote the campaign of House hopeful Sean Duffy.

Calling the Wisconsin county prosecutor “one of the rising stars in the Republican Party” with a “commonsense vision to tackle the economic problems and reckless spending our country faces,” Pawlenty sent a mailer to his Freedom First political action committee’s e-mail list announcing that the two would co-host a Facebook town hall on Friday.

The mailer and online session are two of the three prizes Pawlenty, a potential 2012 presidential candidate, promised to Duffy as winner of an online promotional event.

The third is a matching dollar for every dollar the PAC helps Duffy raise — up to the $5,000 limit.

Duffy is running in the 7th district, where Rep. David Obey (D) is retiring, and Democratic officials have rallied around state Sen. Julie Lassa as their nominee.

“Democrats have brokered a backroom deal that puts all of their resources behind one candidate in a desperate attempt to hold onto this seat,” Pawlenty said in Wednesday’s e-mail. “Their hand-picked candidate will continue to promote big government and irresponsible spending which is why we need to help Sean today.”
