Healthcare Reform without Tom Daschle

Tom Daschle was key to making good on the Obama campaign's major promise of better access to healthcare for all Americans. Today, the former Senate leader withdrew his nomination to avoid what he called “distraction,” apparently the flap over unpaid federal taxes. We hear more about the politics of the White House and Congress, and look at what this could mean for healthcare reform. If a single-payer system run by the government is off the table, what about extending Medicare or care for veterans?  Is that what Republicans call “nationalization?”  What about dealing with rising costs, especially for treatment that's not really needed?
