DON'T GET YOUR KNICKERS IN A KNOT!

It's time for a story.
Once upon a time, a Republican President nominated a fella to the supreme court.
Congress happend to be controlled by the Republicans,
And, the nomination passed without any major incidents.

But, that's not the end of the story.
You see, the justice was named Earl Warren, and Earl turned out to be way more liberal than anyone ever suspected.
In fact, Earl Warren was not at all what Ike expected (and Eisenhower later commented that nomination was the "the biggest damned fool mistake I've ever made in my life").

The moral of the story is - SHUT UP!
We have no idea what kind of justice Alito is going to be.
Congress can make sure that he's qualified, make sure he's not a wacko, and certainly give him a hard time, but once a person gets a lifetime appointment, they're free to go completely wacko.
