Huck PAC, the political action committee of former Arkansas Gov. Mike Huckabee, contributed $2,500 to the gubernatorial campaign of Bob Vander Plaats, according to paperwork filed Friday with the Federal Election Commission.

The 2008 winner of the GOP Iowa Caucuses raised $304,673 during the first six months of 2009 for his PAC and disbursed $336,589, donating only $17,500 to candidates across the country. On the last day of the filing period, Huck PAC gave $2,500 to Team Vander Plaats. (The PAC paid out $131,000 in payroll and benefits for its employees, and it spent $72,100 for fundraising-related expenses.)

Huckabee endorsed Vander Plaats’ candidacy in June, keynoting a fundraiser for the Sioux City businessman that the campaign said brought in around $80,000 (gubernatorial candidates won’t file financial disclosure with the state until January). Vander Plaats was Huckabee’s Iowa campaign director during the 2007-2008 presidential caucus season.

Free and Strong America PAC, the political action committee of Huckabee’s caucus rival, Mitt Romney, contributed no money to Iowa campaigns so far this year.
