WASHINGTON -- Political forecaster Stu Rothenberg says the open seat in Minnesota's Second Congressional District is a "toss up" next year -- meaning it is among only 12 seats out of 435 he says could swing either way.

In his latest forecasting report, Rothenberg calls Democratic Rep. Collin Peterson a "safe Democrat" and Democratic Rep. Rick Nolan's seat "Democrat Favored."

In the Seventh, Peterson handily won his seat in 2014, even though national GOP groups pumped $8 million into the race to try and portray the congressman as a creature of Washington. No Republican has stepped up so far to run against Peterson next year.

Republican Stewart Mills will run again against Nolan in the Eighth Congressional District. Nolan won the seat last year by just over 3,000 votes.

The Second district currently has six people -- two Dems and four Republicans -- duking it out ahead of the next year's primaries. In the running are Democrats Angie Craig and Mary Lawrence and Republicans David Gerson, John Howe, Pam Myhra and Jason Lewis.
