They’re going to protest shutdown the government repeatedly the rest of the admin because it worked better for them than for the GOP.

The media is running cover for them as usual which may or may not deflect the blame that the GOP would have gotten if the situation was reversed. Other than that they didn't walk away with anything they weren't already being offered before the shutdown. In that sense it didn't work any better for them than it did for the GOP.

That's not to say they won't do what you're predicting. The GOP's rare failure to snatch defeat from the jaws of victory makes it less likely, but far from impossible. The Dems' main motivation is to put on show for their lunatic base, and they'll be just as eager to do that in January. Having to bend over like a bitch afterwards nullifies any benefit any political benefit they would otherwise gain, but we're not dealing with rational people here. They never would have shut down the government if we were.
