Very good point! This, however, has morphed into something other than ObamaCare and what it's morphed into is still a win-win situation for the conservatives if only they hold their ground.
The President refuses to negotiate and feels he can stop the shutdown and even raise the debt ceiling without negotiating with the House. THIS is what it's morphed into.
And also a good point. To help keep the focus, the House should continue to offer bills to fund everything but the ACA.
