As I type this, I've just returned from the ballroom where Laura Ingraham is introducing Mitt Romney. The room is shut down -- filled to capacity -- literally. People seem stunned to hear that Romney has pulled out... or will pull out. McCain's people here are eagerly spreading the word that Kevin Madden has confirmed Romney's withdrawal.

And there seem to be more McCain people here as the day goes on -- young and old. They're still a minority by far, but they seem eager to fill the void that Romney is apparently about to leave.

More after Romney concludes his speech...

Editor: Romney spokesmen Kevin Madden just sent this excerpt from Romney's speech, which he is in the midst of delivering:

If I fight on in my campaign, all the way to the convention, I would forestall the launch of a national campaign and make it more likely that Senator Clinton or Obama would win. And in this time of war, I simply cannot let my campaign, be a part of aiding a surrender to terror.

This is not an easy decision for me. I hate to lose. My family, my friends and our supporters... many of you right here in this room... have given a great deal to get me where I have a shot at becoming President. If this were only about me, I would go on. But I entered this race because I love America, and because I love America, I feel I must now stand aside, for our party and for our country.

I will continue to stand for conservative principles; I will fight alongside you for all the things we believe in. And one of those things is that we cannot allow the next President of the United States to retreat in the face evil extremism!!
