Dick Durban thinks the Democrats may walk out on it (which would only mean they will get a worse deal after the GOP takes over the House next year).
Well, no..... the House generates revenue bills, but they have to be passed by both houses and signed by the president before they become law.
If the Democrats are politically savvy (and they are), they will walk out on the deal, and stonewall anything they don't like in the next session. It's a perfect setup for the usual "Nice Democrats vs. Mean Republicans" gambit, and you know whose side the media will be on.
If the R's take a hard line now, it probably helps Obama and the Democrats in general.
The R's can probably get something passed and signed into law -- something that won't be perfect, but it will be better than the "nothing" that the purists will get if they insist on perfection.
And then, next year, they can do it again and get a little more.
That would work for them IF they hadn't spent the last eight years saying the GOP was the "party of NO." If they now become the party of no, the Republicans will use that very effectively against them.
