Why wouldn't the GOP take the blame, feel the heat, as it were, not the President?
Isn't it the mission of "winning" in politics to see your ideas win in that way, too?
The President is NOT going to get "points" for being "responsible" if he doesn't go out there and sell, sell, sell himself as the responsible one in the room. As long as he cuts-taxes-and-spends in the fashion of the GOP, he gives too much ground, if he doesn't win the political fight, in terms of public opinion.
The way I look at it, they had a chance in a lifetime to take the whip-handle on the GOP's brand, to expose their overplayed hand; but they blew it with a quick-fire deal, however well conceived.
