What should bother Tea Party conservatives, deeply, is the anti-democratic nature of the shutdown.
"It’s worth remembering that in the early nineteen-sixties, when another health-care bill was under debate, the rhetoric of the Republicans who opposed it was just as over the top. We didn’t get socialism, as those opponents warned; we got Medicare, which turned out to be a very popular, mostly high-functioning program that saves elderly people from going bankrupt when they get sick. In the end, as the President says, that is the kind of outcome that the extremist Republicans running this budget battle fear the most: that Obamacare will work, and the Democrats will get credit for it. And what the mainstream Republicans fear the most is that voters will blame them for letting the lemmings run the show. If Obama refuses to back down, this could be a moment that will define his legacy—a fight for democracy as much as for Democrats."
