The most likely solution to passing healthcare reform if Coakley loses tomorrow appears to be this: the House passes the Senate bill, and the president signs it. The Senate agrees to pass the House amendments via reconciliation in the budget bill.
But as Jonathan Cohn and Steve Benen suggest, a Coakley loss could scare some of the moderate and Blue Dog House Democrats into voting against the bill -- thus the House doesn't reach the 218 threshold for passing the Senate bill.
The kill-billers might actually get their wish here.
