Of course, I really wish he would grow some balls and actually do that - the people he would lose are already lost, and actually getting something done would, I think, energize his base and maybe sway some moderates. Unfortunately, he's just fobbing this off on Congress so there's less risk to his political image.
You say this right after he GOT this passed. And it had to be a bi-partisan effort (to some degree at any rate) due to the super-majority requirement caused by the GOP filibuster system. If he shat all over the GOP he wouldn't have been able to sweet talk any of them over the fence and would have never gotten this passed.
It sure ain't sexy but this is how it has to be with current political climate and filibuster rules.
