Now that both the House and Senate have passed health care reform bills, all Democrats have to do is work out a compromise between the two versions. And it appears they’re not about to let the Republicans gum up the works again. According to a pair of senior Capitol Hill staffers, one from each chamber, House and Senate Democrats are “almost certain” to negotiate informally rather than convene a formal conference committee. Doing so would allow Democrats to avoid a series of procedural steps–not least among them, a series of special motions in the Senate, each requiring a vote with full debate–that Republicans could use to stall deliberations, just as they did in November and December. “There will almost certainly be full negotiations but no formal conference,” the House staffer says. “There are too many procedural hurdles to go the formal conference route in the Senate.”
