John McCain Stops Changed to Medicad

In a direct challenge to Democratic leadership, Sen. John McCain (R-Ariz.) introduced an amendment on Thursday night that would prohibit Congress from using reconciliation to make changes to Medicare.
Framed as an effort to protect the sanctity of entitlement programs, McCain's measure would deprive Democrats of a stream of revenue for their health care bill. The party has targeted hundreds of billions of dollars in cuts and savings to the Medicare program that it would turn around and use to pay for other reforms.
