Roll Call says two Democratic members of Minnesota’s congressional delegation -- Sen. Al Franken and Rep. Rick Nolan -- could face tough re-election races this fall.

According to the Capitol Hill newspaper, Franken is among the 10 most vulnerable senators this election cycle, but is “probably headed back to the Senate.”

The piece notes that Franken “drew strong Republican opponent in Mike McFadden, a businessman with fundraising chops.” McFadden faces state Rep. Jim Abeler in Tuesday’s GOP primary.

Noting Stewart Mills III’s campaign in the Eighth Congressional District, the paper says Nolan is among the 10 most vulnerable House members. Roll Call rates the Eighth Congressional District race as “leans Democratic,” meaning Nolan remains favored to win. The Cook Political Report rates the race as a “toss-up.”

Here’s the passage on Franken:

Franken is sitting on $5 million in a state Obama won twice, giving him a decided edge in his race for re-election. But Franken drew a strong Republican opponent in Mike McFadden, a businessman with fundraising chops to make it competitive, and the personal resources to help his campaign along. Even Minnesota Democrats acknowledge it will likely be tight. But, as of right now, Franken is probably headed back to the Senate.

Here’s what Roll Call had to say about the Nolan-Mills race:

After a three-decade hiatus from the House, Nolan defeated a one-term member last cycle and came back to Congress. This November, Nolan faces a well-financed foe in businessman Stewart Mills, who is capable of self-funding. Mills is well-known among the district’s residents because of his family’s chain of popular farm and sporting goods equipment stores.

Democratic operatives add that while the district favors Democrats, it has grown more competitive over the years. What’s more, Nolan’s distaste for fundraising could put him at a disadvantage in the fall.
