Anyone who makes a deal based on a promise is a fool. Especially a Democratic promise.
The Unholy 7 may gets some of Bush's lower court nominees through, but the SC fight is on its way, and the Dems still have their filibuster.
Let's not forget that the Democrats had no problem changing the Constitution by "suggesting" that the President give up his sole authority to nominate judges. Now the Dems want to be "consulted" first. How can anybody trust a Democrat who would unconstitutionally change the Constitution in a back room deal?
If the Democrats break their word (which could be likely) then the "Unholy 7" have no out---they must support the filibuster. And they have to support it for more than just moral reasons.---Political reasons. This goes even more so for McCain.
And the Pubbies still have their nuke option.
