A new Rasmussen Reports telephone survey of likely voters in Minnesota finds that 50 percent of voters in the state approve of the job Senator Al Franken is doing, including 25 percent who strongly approve. That's unchanged from surveys in November and January. On the other side of the ledger, 46 percent disapprove, 31 percent strongly.

Meanwhile, Rasmussen found that 67 percent approve of how Senator Amy Klobuchar is performing, with 42 percent who approve strongly. The overall approval rating is a nine-point increase from November. Just 30 percent disapprove of Klobuchar, including 15 percent who strongly disapprove.
