A GOP outside group is accusing Rep. Collin PetersonCollin Clark PetersonThe 9 House Republicans who support background checks Congress must work together and solve humanitarian crisis at the border GOP scores procedural win by securing more funding to enforce Iran sanctions MORE (D-Minn.) of not being "Minnesota nice" in a new television ad.

The ad from the American Future Fund accuses Peterson of ignoring his constituents.


"Minnesotans work hard to get by in this economy and we deserve answers from Congressman Peterson. He’s been in Washington for decades and the choices he makes affect our lives. So where is he when we want answers?" the ad's narrator asks. "Tell Collin Peterson if he’s lost his Minnesota nice, he’s been in Washington too long."

Peterson has long represented a Republican-leaning northern Minnesota district. His fundraising has been slow so far this year and he hasn't said whether he'll definitely run again. Republicans have been targeting him in the hopes that he'll get tired of the attacks and decide to retire.

If Peterson runs, the Agriculture Committee ranking member will be tough to beat, but if he decides to retire the seat could be a prime GOP pickup opportunity.
