OK, apparently none of you know What To Think(tm) about the health care summit, so I will tell you.
1. The biggest breakthrough was to bring Republican opposition down to earth. Any notion that the Democratic approach is illegitimate, un-Patriotic, etc., was absent, and the lingering effects of this event will make it just a bit harder fro the GOP to continue down that path. The President ("I like calling you that") made them sit up and behave, and made them spit out their stupid ideas in a way that they couldn't be ignored.
2. This was the next step in creating the fissure that will ultimately sever the crazy out of the GOP. For some of those GOPers, like Coburn, for example, there was simply too much temptation to participate in the substance, which means one cannot pretend that the entire undertaking is bogus. See #1.
3. The President modelled how to both confront these guys and stay civil. Several Dems were already pretty solid on this (Clyburn comes first to mind), but many of them got a chance to show that they too could act like grown-ups.
4. It would be pretty hard for any fair-minded viewer of the event to conclude that the GOP was serious in its thinking, or that the Dems hadn't thought pretty hard about their proposal.
5. This event, together with the one in Baltimore, will be remembered for being a sort of watershed for both the Dems and the GOP.
6. Importantly, the GOP was without one its main tactics: shouting down those who would show you to be a liar. The President felt comfortable speaking over fairly vociferous GOPers when he felt that had gone too far. I think this will give a lot of other Dems the courage to do the same, with the effect that their voices won't be drowned out so easily or so often.
7. The event ensures the passage of HCR, and for that matter much else.
8. By staking everything on their nutty worldview, the GOP bet the farm and lost. If they cannot persuade enough voters that government action inherently wrong, they've got nothin.
9. Anyone watching the event would have to conclude that a fair portion of the GOP's senior-most leaders are venal and not bright.
10. Speaking of not bright, how 'bout that Chris Matthews? Even next to dim-witted Chuck Todd he STILL seems dumb.
That is all.
