The analysis you linked to is weak. The nuclear option is OFF the table for the 109th Congress. The republican deal makers have sworn not to vote for it, period. The democrats have only agreed not to fillibuster unless the circumstances are extrodinary. Guess who gets to decide extraordinary?
The Republicans have been rolled, your analyst should look for a new line of work and Bush SCOTUS nominees can look forward to fillibustering democrats with 7 RINO dwarfs supporting that fillibuster.
It can't freaking get any worse.
