You know, sarcasm aside, this is an interesting gambit by the GOP. Pass a continuing resolution funding the government except for Obamacare, the Senate will (of course) strip out the Obamacare provision, and the House either retreats or the government "shuts down" (not really, but that's how it will be portrayed).
The GOP is banking on the fact that Obamacare has become so deeply unpopular, and its unintended consequences have become so well publicized - and this is true - that they will finally win the PR battle with respect to a government "shut down." They will argue that they are perfectly willing to funding all programs except Obamacare - and passed a CR doing just that - but the Senate is holding the entire government hostage because it insists that Obamacare be funded. The Dems will argue just the opposite, that the GOP is holding the government hostage by refusing to fund Obamacare. They'll both be right.
My guess is that, even though Obamacare is incredibly unpopular, the GOP will come out on the losing side of public opinion. The Dems' messaging through their MSM allies is simply still too pervasive. Hysteria about a government "shut down" because of GOP intransigence will be in most every newspaper and MSM broadcast.
Still, it's going to put some "blue dog" Senate Dems from states that hate Obamacare in a very tough position...
