This morning brings word that Bob McDonnell, the governor of Virginia, will endorse Mitt Romney and travel to South Carolina to campaign with him.
McDonnell has spoken in the past of his preference for the Republican nominee to have gubernatorial experience, and of his friendship with Rick Perry.
Of course, McDonnell lives in Virginia, where the only names on the ballot will be Romney and Ron Paul. So if McDonnell wanted to endorse a candidate that he could actually support with a vote in the primary, perhaps this decision turned out to be pretty easy.
