Good; Obama has a popular issue to campaign on.
Our public tax debate is so screwed that the best we can hope for is Obama using it to score political points. Of course the buffett rule is PR only. Given Republican control of the house, there is no serious policy Obama could pursue, so why not demagogue away. No Republican in elected office can vote to raise revenue anywhere, any how, except through cuts to spending on the poor. That's the bed the Republicans made and we all have to lie in it, so no, I'm not feeling guilty about Obama somehow debasing the debate and alienating Republicans who have zero influence with how their party actually behaves.
Sam's post was an unexpected bonus of the debate, really.
