Nah, this is the part where the big talkers all threaten to quit the party, never vote for the Republicans again, rebel, etc, and, as you know, none of it ever happens. Some will make veiled references to revolution, but won't actually get out from behind their keyboards. The next time a vote doesn't go well, probably the debt ceiling fight in a couple months, the same people will be claiming to be done with the GOP and we will rerun this whole thing again.
Is our establishment weak and pitiful. Sure, no doubt. Does it represent real conservatism. Nope. But it does represent a majority of the voters in the Republican party who, in reality, mostly don't want the kind of dramatic cuts that are necessary any more than most Democrats do. We have a people problem in this country, not an "establishment" problem. As long as the people do not stand behind politicians that want massive cuts to the social welfare state, then few if any politicians will ever cast those votes.
We are Europe now. On a slow but steady glide path of decline. The public will do everything possible to keep the bloated social welfare state, just like Europeans. So we will kick the can, and kick it again, and kick it more and more often - who knows how much debt we can pile up before our economic house of cards implodes. Maybe years, perhaps another decade or two. But the problem is with our people. The "establishment" is merely a symptom of the bigger problem.
It is time to stand firm, get together, and to continue to push the Republican party to move towards our positions.
