He's hit a nerve.
But even more than that, he showing us what selfless public service and championing principles (regardless of politics) is all about.
And this, too: He's reminding some of us of the days when our leaders had a real sense of purpose and a decent sense of priorities; when they were three-dimensional; when they weren't blow-dried or air-brushed or reconstructed with painted smiles -- when they were real.
He's smoking out all the phonies tonight and you've got to believe he's giving smirky set a case of the chills down there in Washington.
This is a Big Moment.
