In advance of the anticipated House vote to pass health care reform on Sunday, Democratic legislators are "jittery" about the measure. Republicans are playing that up and pressuring their colleagues across the aisle. President Barack Obama is applying counter-pressure.
It's far from the end-game that it's been called. Once the House votes, the package heads back to the Senate, which will take up the measure in that legislative body's "deliberative" way. Republicans are threatening endless procedural delays; Democrats counter they can address any procedural points.
