Minnesota Public Radio's Tom Scheck reports on child advocate Patty Wetterling withdrawing from the U.S. Senate race and endorsing Hennepin County Attorney Amy Klobuchar. Wetterling said she made her decision so the DFL party would unite behind Klobuchar. While many political experts are calling Klobuchar the party's clear front-runner, fellow DFLer Ford Bell says he's in the race until the end.
