Russ Feingold was elected to his third term in the U.S. Senate six years ago with a double digit margin of victory. Now polls show him trailing by double digits.

University of Wisconsin political scientist Charles Franklin says Feingold's challenge is to show voters why his 18 years in the Senate "is an advantage, not a disadvantage."

Franklin points out Republican challenger Ron Johnson was polling almost dead-even with Feingold in hypothetical match-ups back in May. Johnson was a virtual unknown in Wisconsin politics at the time.

Franklin, who helped develop the popular website pollster.com, spoke about the race in an interview with Minnesota Public Radio News host Cathy Wurzer.
