I mean, that's how republicans get what they want. Why are democrats trying so hard to work with republicans? All they end up doing is compromising while republicans get everything they want. Then when republicans are in power, democrats go along because "decorum" or whatever, but if the democrats would obstruct and pull every dirty trick like the republicans, then things wouldn't have gotten this bad.
Because that's the goal, their strategy is working as intended. The Dems don't want something different from the Reps, they just want to be able to feign being opposed so that they can claim the moral high ground. It looks like a token effort because it is.
There is usually no actual problem that Republicans are mad at. Also what makes the Democrats better is they are creating less new actual problems. They don't solve problems very often, either.
The right puts up a razor wire fence along a border town, the left demands they take it down, meanwhile 2 miles upriver is a passable point with no fence at all, yet the show must go on.
They tied a border bill to a Ukrainian and Israeli aid package.
Edit to add: Biden failed by going with the Republican narrative about the border.
He admitted that there was a "crisis" that needed to be fixed and then failed to pass it, now come election time it is a choice between the Democrat who couldn't pass a border package with the Republican politicians or a Republican who will be able to pass legislation to make the border much worse for people trying to cross.
This is America's fault for destabilizing the South American countries for so long that people who want a safe life have to leave their home countries to take a treacherous journey hoping to live in the USA.
