Turns out Senator Obama verbally smacked Lieberman on the Senate floor for spreading the Muslim bullshit... Newsweek via TPM:
In a brief but animated Senate floor confrontation last week, according to a campaign aide who asked for anonymity when talking about private discussions, Obama told Lieberman he was surprised by Lieberman's personal attacks and his half-hearted denials of the false rumors that Obama is a Muslim.
Wait until everyone finds out that Senator McCain is really a Muslim.
