It looks like it's really going to happen. TPM reports:
The White House has given Congressional leaders the all-clear to move ahead on health care reform, with both the House and Senate aiming to pass final legislation by April.
A top aide to House Democratic leadership told TPMDC this morning that tension remains between the House and Senate as members in the lower chamber remain wary the Senate might not honor a promise to fix their bill through reconciliation.
I suspect they need the time to rustle/whip the votes on the House side. The sooner the better because the Republicans are already acting all victimized by a majority vote. Sad little bastards.
