How many government workers could be furloughed?
More than 783,000 government employees, according to a CNN analysis of contingency plans published by the federal government on Friday. Not all government agencies submitted contingency plans.
And will this kill Obamacare?
It probably wouldn't. Most of the money for Obamacare comes from new taxes and fees, as well as from cost cuts to other programs like Medicare and other types of funding that would continue even if the government shuts down.
Is there any hope if a deal isn't struck by midnight?
If lawmakers reach an agreement by late Monday night, but the funding bill hasn't made it to the president's desk, the government can ignore a short lapse in funding and carry on in good faith knowing that it will. The last time that happened was April 2011.
