Sure, Obama’s got Oprah, but he’s not the only candidate basking in the glow of a little star wattage. John Edwards got Kevin Bacon to warm up the crowd for him this Sunday at an Ames, Iowa high school cafeteria.

Edwards is the only candidate who’s called for a moratorium on building more factory farms like the humongous hog operations that have sprung up all over Iowa, creating huge manure lagoons that spew toxins into the soil and air. But can Bacon bring home the voters for Edwards? Bacon downplayed his influence to the Des Moines Register:

“”people will make up their own minds, not based on anything I say. But if there’s a couple more people here because I’m here, and they get a chance to hear what Senator Edwards says, that’s what’s important.”
