Richardson tells Clintons to move on

After feuding with Hillary Clinton supporters for days about his endorsement of Barack Obama, Bill Richardson has a simple message for them: Get over it.

Appearing on CNN Wednesday, the New Mexico governor categorically denied that he had told Bill Clinton that he would not endorse Obama -- as the former president reportedly told Democratic leaders in California recently.

Another one of those accusing Richardson of going back on his word, James Carville, has called Richardson a Judas for what he described as an act of betrayal for accepting high posts in Bill Clinton's administration -- then stiffing the former first lady when she needed his endorsement.

Richardson told CNN that he was close to endorsing her, but backed off when the campaign got nasty. When he announced his support for Obama last month, he called him a "once-in-a-lifetime leader."

"The Clintons should get over this," Richardson said on CNN.
