Let's talk numbers.
The republicans held up 60 of Clintons judges. Locked up in committee, they never got an up or down vote on the floor of the Senate.
The Dems have filibustered 10 of bush's judges. Since then, three have removed themselves from consideration, and three the Dems have agreed to compromise on.
So, the Dems are only holding up 4 of bush's judges.
So now the Dems have two choices. They can fight, or they can compromise.
If they fight, the good news for the Dems is that most of America is already on their side. Infact, even 53% of republicans support their use of the filibuster.
A long drawn out battle would likely end up costing the republicans the majority in the Senate. In which case, the Democrats won't need the filibuster, anyway.
If they compromise, they'll still have the filibuster, as an ace in the hole, should bush try to slip an extremist onto the Supreme Court.
Either way, it looks like the Dems are going to come out of this one ahead.
