John McCain will endorse Mitt Romney

After the Iowa upset, McCain is supporting Mittens:

McCain and Romney were bitter foes in 2008, but Romney repaired the relationship after his defeat with a season of determined campaigning for his former rival.

The endorsement will offer the Romney campaign a pivot point after the virtual tie with Senator Rick Santorum in Iowa, and a growing impression that the former governor is uniting the party behind him.
McCain is unlikely, however, to appeal to the conservative Republicans who are skeptical of both men.

This is a beautiful mess.
