As we all know, they never needed the Republicans cooperation since they have a filibuster-proof majority:

Given hardening Republican opposition to Congressional health care proposals, Democrats now say they see little chance of the minority’s cooperation in approving any overhaul, and are increasingly focused on drawing support for a final plan from within their own ranks.
[…]
“The Republican leadership,” Mr. Emanuel said, “has made a strategic decision that defeating President Obama’s health care proposal is more important for their political goals than solving the health insurance problems that Americans face every day.”
[…]
The Democratic shift may not make producing a final bill much easier. The party must still reconcile the views of moderate and conservative Democrats worried about the cost and scope of the legislation with those of more liberal lawmakers determined to win a government-run insurance option to compete with private insurers.

It will be interesting to see if the moderate Democrats in the Senate will cave on the public option because it doesn’t look like the lefties in the House will.
