In a new radio ad running in southwest Virginia, bluegrass legend Ralph Stanley speaks out on behalf of Barack Obama. "I think I know a little something about the families around here," he says. "We all need a change." The Grammy winner is so popular in his home state, bumper stickers proclaiming "Ralph Stanley for President" popped up in the 1970s, according to the Wall Street Journal. With his endorsement, Stanley joins a chorus of artists rallying behind the Democratic candidate, including Bruce Springsteen, Billy Joel, Kanye West, Stevie Wonder and the Grateful Dead.
