Senate Blue Dogs warn Reid: You'd better not cave to the House on ObamaCare

Sens. Mary Landrieu (D-La.), Blanche Lincoln (D-Ark.) and Ben Nelson (D-Neb.) have made clear there is little room to deviate from the bill the Senate passed on Christmas Eve.

They are the most vocal of nearly two-dozen senators who have indicated they see little wiggle room in the conference talks.

Centrists have said they will not vote for a healthcare reform bill that imposes a tax surcharge on the nation’s highest income earners or reduces the tax burden on so-called Cadillac health insurance plans, which are held by many unionized workers.
