"Can you be a bit more specific as to what the more immediate consequences are, and how they lead into the rather grim picture you've painted? So in this hypothetical scenario, some things get funded, other things do not get funded. What does that actually mean?"
If there's partial funding, then the political pressure on the Republicans to end their obstruction at all costs strategy eases immensely. Then, the Republicans have no real incentive to actually negotiate in good faith. Indeed, at that point, all the incentives favor intensifying their stance, given that there's no real political cost they'd have to pay for obstructing the funding of anything their base doesn't like, and a real risk of being primaried out of a job if they do compromise.
In the long term, with demographics being the way they're moving, the Republicans have to rely upon increasingly stringent methods to try and keep anyone who isn't a rich white dude from voting effectively. Given the composition of the courts, and the bottomless well of cash they have to draw from in their eagerness to aid in the upward redistribution of wealth, they'll probably succeed in these efforts. After a couple of generations of assisting in the selloff of America's infrastructure, we'll be a third world nation, although to be fair, by that time, given the increasing concentration of wealth worldwide, nations won't mean very much. At some point, the military starts seeing more and more of their family getting utterly screwed to maintain the good life for a handful of wealthy neo aristocrats, and starts radicalizing. From there, it's a short leap to a Committee for Public Safety, although, if the superwealthy prove more capable than I suspect they will after a couple of generations of expecting private profit but socialized risk as their birthright, they may be able to gin up a convenient "other" and steer us into right wing fascism instead.
To sum up: I tend to be a liberal because distribution of wealth and mobility of class matters, and modern day conservativism seems to be about concentrating wealth and diminishing class mobility, which accords with what happens whenever humans have let an oligarchy consolidate power in a society.
