U.S. Sen. Al Franken is likely to lead GOP challengers in the 2014 election, according to a new poll by Public Policy Polling released Tuesday.
In a survey of 712 Minnesotans between May 17-19, 51 percent of voters in Minnesota approve of the job that Franken is doing and 42 percent disapprove.
The margin of error is 3.7 percent.
When pitted against potential Republican opponents, Franken still comes out on top.
The poll shows 51 percent would vote for Franken over investment banker Mike McFadden and Hennepin County Sheriff Rich Stanek. Only 36 percent said they's vote for McFadden and Stanek.
Against state Sen. Julie Rosen, R-Fairmont, 52 percent would pick Franken versus 36 percent that said they would choose Rosen.
The senator also has a 17 percent lead over state Sen. Julianne Ortman, R-Chanhassen, radio talk show host Jason Lewis and U.S. Rep Michele Bachmann--who's already launched her campaign for Congress and not likely to join the Senate race.
The poll shows 60 percent of voters have a negative opinion of Bachmann.
None of the hypothetical challengers have officially announced they're running against Franken, the Pioneer Press reports.
MPR says two potential candidates who pulled their names from consideration early were former Gov. Tim Pawlenty and former U.S. Sen. Norm Coleman. Also, U.S. Reps. John Kline and Erik Paulsen have also declined a U.S. Senate bid.
