A GOP outside group is accusing Rep. Collin Peterson (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.
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.
