For some Democrats and most Republicans, a denouement of Democratic defeat was predictable. Still, few leaders have executed the rare double-buckle as quickly or fully as Schumer.

First, the activist wing of the party pushed Schumer to hold government funding hostage to an immigration deal. He bowed to their demands, leading most Democrats to vote against a stopgap spending bill on Friday night.

But once they’d gone over the cliff — voting to shut down the government — many members of his own caucus, including Democrats who are running for re-election this year in states Trump won, started pushing Schumer to back down. They worried about the backlash from voters who care more about their government operating than the fate of the Dreamers. Under duress from that set of senators, Schumer folded again.

“It was pretty evident by Saturday that a bunch of his members were getting nervous, and that as much as he tried to keep them together, they were looking for an out,” said Jim Manley, a former Democratic leadership aide. “The 2018 elections are still going to be a referendum on Trump — and none of this shutdown stuff is going to change that. Democrats live to fight another day.”

And if there’s no deal for the Dreamers and McConnell isn’t ready to bring up an immigration bill in the Senate by Feb. 8, Democrats could reprise their shutdown strategy at that time.

But former McConnell chief of staff Josh Holmes said Schumer, the rookie Democratic leader, miscalculated against his veteran GOP counterpart.

“They were dealing with someone who has seen this movie before and knew how it was going to play out,” he said.

Some Democratic strategists said Schumer got enough to justify re-opening the government.

“The best strategy was and is to resolve [the Dreamer issue] without the added jumble of other nonimmigration political and policy issues,” said Democratic strategist Chris Kofinis. “Getting a commitment from McConnell to do that is a victory for Schumer. Now, the question is, what happens if the Republicans and Trump don’t live up to that bargain and it all breaks down again?”

But Rebecca Katz, a former Senate Democratic leadership aide, saw weakness from her party’s leaders.

“Imagine what Democrats could accomplish if they had a backbone,” she said.
