Harry Reid is having a fun day:
It's true. Back when he was Senate whip in 2005, Mitch McConnell helped lead the Senate Republican effort to change the filibuster rules.

By filibustering 10 qualified judicial nominees in only 16 months, our Democratic colleagues have broken this unwritten rule. This is not the first time a minority of senators has upset a Senate tradition or practice and the current Senate majority intends to do what the majority in the Senate has often done: use it's constitutional authority under Article 1, section 5 to reform Senate procedure by a simple majority vote.
In two sentences 2005 McConnell destroys all of 2013 McConnell's arguments. Just like that. What a difference a Democratic president makes.
