Multiple sources report that Romney is getting out of the race today at CPAC.
Pre-released announcement here:
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 listened to the whole speech and this passage did indeed appear nearly at the every end. The first part of the speech began with an appeal to American exceptionalism and moved on to red meat conservatism with a Mormon twist (talking about families and morality as the basis of national prosperity and strength, e.g.). He then announced he was getting out and made another heartfelt appeal to American exceptionalism.
With the exception of his faith speech, nothing in this race became Romney so much as the way he left it.
