House Minority Leader Nancy Pelosi on Tuesday called the proposal "a decision to default." And speaking on the Senate floor, Reid said, "Extremist Republicans in the House of Representatives are attempting to torpedo the Senate's bipartisan progress with a bill that can't pass the Senate."
Even Sen. Bob Corker, R-Tennessee, said it was time to get a deal done after lengthy delays he blamed on the unrealistic goal set by GOP conservatives of gutting Obamacare.
"The fact is we've got to figure out a way to move ahead," he told CNN's "New Day" on Tuesday. "In fairness, on our side of the aisle, we've wasted two months, focused on something that was never going to happen."
World watching Washington
The Senate is indeed moving ahead, with legislation that would give Republicans some concessions while overall being closer to what Obama and fellow Democrats have long pushed for regarding government funding and the debt ceiling.
The fight began when Republicans -- paced by Sen. Ted Cruz of Texas -- insisted that they'd only allow the government to open fully into the start of the fiscal year October 1 with amendments to defund or delay Obamacare.
Alas, the only element of the Affordable Care Act that would change under the pending Senate deal is an anti-fraud provision requiring income verification for people getting federal subsidies, according to a Democratic source.
Even if a deal is finalized soon, that doesn't mean it will become law right away.
The earliest a vote might happen is late Thursday or in the pre-dawn hours of Friday, assuming Boehner sends a "message" allowing the Senate to expedite its vote.
If there's not unanimous consent by senators -- in other words, if a tea party conservative like Cruz has an issue -- a final vote would be pushed to Saturday, at the earliest. The delay for a final Senate vote could stretch seven to 10 days, if some chamber members throw up yet more procedural hurdles.
The prolonged legislative process, not to mention the threat of yet more stalemate, could wreak havoc in financial circles.
The partial shutdown has proved costly, leaving hundreds of thousands of federal employees are either idle at home or not being paid while working not to mention the costs of shuttered aid programs and closed parks.
And it's not just Americans who could be impacted without action to address the U.S. government's debt situation.
Jon Cunliffe, who will become the deputy governor of the Bank of England, told British lawmakers over the weekend that banks should begin planning for contingencies.
And officials warn that tough choices are ahead about which bills to pay and which to let slide, should the shutdown and debt ceiling debate drag on.
Even before the deadline, the stalemate was taking its toll. Mark Zandi of Moody's Analytics told CNN's Christine Romans on Tuesday that the standoff has cost the economy about $20 billion in gross domestic product. GDP is a measure of the goods and services produced by an economy.
