This is a middle ground - at least we can say we passed a bill that stops the vast majority of taxes from going up and Reid and Obama would not pass it. It isn't much cover, but it's all we have. See how quickly they panned it - they know it looks better for the GOP.
I know- we already passed similar laws that sit collecting dust in the Senate. This is a little different, because even the “Jaywalking” masses are paying a little attention (at least those few that pay taxes).
Many on the right will presumably not go for it. But some Dems will.
