Iowa Congressman Greg Ganske of Des Moines is making the move to challenge U-S Senator Tom Harkin in 2002.Ganske, a republican who was elected to Congress in 1994, is a plastic surgeon representing the fourth district. Ganske has filed some financial papers, and sent out a letter to raise money for his Senate race, saying he wants to “take Harkin to the mat.” Ganske was a wrestler in high school. During his political career, Ganske has split with his party in supporting a Patients’ Bill of Rights. Just last week, Ganske and Harkin appeared at a news conference together to tout a new version of that bill. Ganske represents Iowa’s fourth congressional district which stretches from Council Bluffs to Des Moines. As he was running for re-election to his Congressional seat last year, Ganske ran a radio ad attacking Harkin.
