Dean was supporting the bill with the Medicare buy-in but that has changed now:

In a blow to the bill grinding through the Senate, Howard Dean bluntly called for the bill to be killed in a pre-recorded interview set to air later this afternoon, denouncing it as “the collapse of health care reform in the United States Senate,” the reporter who conducted the interview tells me.

Dean said the removal of the Medicare buy-in made the bill not worth supporting, and urged Dem leaders to start over with the process of reconciliation in the interview, which is set to air at 5:50 PM today on Vermont Public Radio, reporter Bob Kinzel confirms to me.

I believe we will see more big names say the same thing as the day progresses.
