Topeka ? An Iowa-based organization has been sponsoring television ads critical of Democratic Kansas Attorney General Steve Six as he seeks to stay in office.

The 30-second spots on health reform are backed by American Future Fund, a conservative advocacy organization based in Des Moines.

The Topeka Capital-Journal reports that the nonprofit group led by Republicans invested more than $7 million on behalf of GOP candidates in this midterm election cycle.

Published reports indicate American Future Fund was formed Aug. 7, 2007, and participated in the 2008 election cycle by investing in congressional races in several states. The president of the organization is Sandy Greiner, a farmer who served 16 years in the Iowa Legislature.

American Future Fund describes itself as a multistate advocacy group dedicated to promoting “conservative free-market principles to the citizens of America.” In September, politicians considered liberal from a dozen states were targeted by

$4 million in ads by American Future Fund.

Six is running against Derek Schmidt, the GOP attorney general candidate. The third candidate for attorney general is Libertarian Dennis Hawver.

The commercial running in Kansas says Six is a collaborator with President Barack Obama and congressional Democrats responsible for passing legislation expanding health coverage. The ad praises Schmidt for placing interests of Kansans ahead of “partisan politics” on health care.

Jackie McClaskey, spokeswoman for Schmidt, said she wasn’t aware of American Future Fund’s interest in the Kansas attorney general campaign until the ad appeared last week on radio and television. She said the TV ad buy could exceed $300,000.
