Country music star Carrie Underwood has sharp words for celebrities who endorse political candidates. 

"I lose all respect for celebrities when they back a candidate," the "American Idol" winner tells TV Guide in its issue hitting newsstands November 6.  

"It's saying that the American public isn't smart enough to make their own decisions," she explains. "I would never want anybody to vote for anything or anybody just because I told them to. Music is where you go to get away from all the BS. Whether it's from politics or just the world around you, music should be an escape."
