Before the vice presidential debate in Danville, Kentucky, last night, MSNBC's Chris Matthews interviewed people outside the debate site.
While Matthews was interviewing a supporter of President Obama, a woman off-camera yelled out "He's a communist!"
Matthews later interviewed the woman who yelled the insult and asked her why she thought President Obama was a communist.
The unidentified woman said: "All you have to do is study it out, just study it out and you'll see. You haven't done your homework, buddy. He's a communist and those of us who are not voting for him know it."
When pressed by Matthews by what she meant by "Communist," the woman said: "You don't know? You don't know?"
Matthews asked her what she meant again. Once again, she failed to provide proof of her claim, saying: "You just study it out."
Moments later, the woman denied that President Obama was an American, but then added: "Just because he was born here doesn't mean he thinks like us, he's a communist."
