That is a tea party Republican getting basically what he deserves from an increasingly rabid base. It's Rep. Robert Pittenger (R-NC) being forced to 'fess up to his constituents that it's all been a big lie: House Republicans can't kill Obamacare and that he's a no vote on shutting down government to defund because the tactic will not work.
That's not good enough for his audience, however. When Pittenger explains that there's no way the Senate and the president will go along with the scheme, that they just can't make it happen, one audience member yells "It doesn’t matter. We need to show the American people we stand for conservative values."
It doesn't matter. It doesn't matter that Pittenger cosponsored at least a dozen Obamacare repeal bills, and that he says he "supports" the effort of defunding Obamacare. That's not good enough for the rabid base; the base that Pittenger and his allies created.
Republicans have made an entire industry, and got elected, by telling the gullible that if they threw enough tantrums and held their breath long enough, they could make Obamacare go away. That's after the law passed. That's after dozens of failed repeal votes. That's after a fucking Supreme Court decision saying the law is valid. After all that, these elected Republicans kept promising their base that they could get rid of Obamacare.
So of course the people they've been lying to for all these years are going to latch onto the snake oil Sens. Marco Rubio and Mike Lee are peddling, that a simple government shutdown will do the trick. Never mind the reality that it simply can't: Obamacare is funded by mandatory spending, the spending that still continues even in a government shutdown. And never mind that a government shutdown is the kiss of death to Republican hopes for a Senate majority and potentially even retaining the House, and certainly for regaining the White House in three years.
It doesn't matter to the monster that Republicans created. It doesn't matter to the base that Republicans allowed to take over the party because the cash cow of Obamacare repeal was just too tempting, too easy. And now that it's not so easy anymore and their monster is turning on them, the Republicans are getting exactly what they deserve.
