In that event, Speaker John Boehner (R-OH) would have to come up with yet another stopgap bill that includes extraneous measures, or cave and accept a clean CR.
"We will be right back at square one yet again," the Senate Democratic aide said. "House Republicans simply have to choose whether to put the Senate's clean CR on the floor and let it pass with Democratic and Republican votes, or force a Republican government shutdown."
The new House GOP bill delays the Affordable Care Act's individual mandate for one year and prohibits members of Congress and staff from receiving health care subsidies under the law.
"I would like to see Obamacare in hell," Rep. Trent Franks (R-AZ) told reporters Monday night.
Republicans fumed that the portion of the law grants "special treatment" to Congress. It has become a rallying cry among conservatives, but the reality is less simple. Members and staff are required to drop their existing government plans and buy insurance on the Obamacare exchanges, and the health care law provides them subsidies up to a point -- as it provides others who buy from the marketplaces. The GOP amendment would essentially strip them of their employer contribution.
"All the president has to do is say yes, and the government is funded tomorrow," Boehner said on the House floor before the vote.
Many federal services will close and hundreds of thousands of workers will be furloughed if the government shuts down when the new fiscal year begins on Tuesday.
