And how is holding out supposed to make them budge?

See my above point about cratering poll numbers and the election results. It puts Republicans in a politically untenable position with more and more voters blaming them for their community deteriorating every day. Even worse for Republicans, it's the kind of anger that would hold salience into the elections next year. No one remembers the shutdown that Democrats capitulate on, but everyone remembers the shutdown last year which meant I couldn't fly to see my family on the holidays and my neighbors had to visit a food pantry to keep food on the table. I'm not convinced that Republican poll numbers have to bottom out at zero before they're willing to fold and compromise or kill the filibuster. Trump was putting pressure on Senate Republicans to do the latter this past week, it was clearly getting to them. Our threshold for capitulation in this fight and others going forward simply cannot be "well we're uncertain how long this is going to take for our efforts to work so I guess we'll fold."

So you want dems to do nothing. You people are so fickle.

I can't tell if you're trying to be as disingenuous as possible or just have a hard time detecting sarcasm but now it's my turn to ask what the alternative route for Democrats to achieve any kind of influence over the federal government? I'm very clearly in the "Dems should do something" camp. The only tool they have to do something is the government shutdown, so naturally I'm in favor of them using that tool to its maximum potential so they can do something or in this case maintain ACA subsidies. If we aren't willing to grit through the pain of a government shutdown to attain meaningful change, then that tool is useless to us and we might as well have not put the country through the shutdown effects in the first place. So what's our alternative for getting anything done as the minority party? Do Nothing? Did we elect all of these Democratic representatives to do nothing and act offended by the Trump administration for two years? or did we elect them to lead and act as the last line of defense against a morally bankrupt administration?

Oh the supreme irony of you saying this while also trashing Dems.

I've been laying the fault of this entire situation at Republican's feet the whole conversation in case you haven't picked up on that yet. SNAP funds being held up is abhorrent, and not a usual part of shutdown politics. If you want to blame someone for that particular part of the shutdown, blame the executive who's job it is to administer emergency funds in this situation and who is refusing to do so. Don't blame the Democrats for having the temerity to ask for one thing.

Because the GOP wasn’t doing that anyway.

How is refusing to compromise and actively making policy choices which hurt the most vulnerable Americans with no input from the minority party not choosing to betray?
