Former Massachusetts governor Mitt Romney formally announced he's running for the Republican nomination for president.

If you're wondering -- like I am -- where the "Mitt" of Mitt Romney comes from, the always-reliable Vaughn Ververs, Senior Political Editor for CBSNews.com provides this tantalizing detail, from an AP snapshot:

His first name is Willard. He was named for his father's friend J. Willard Marriott. Mitt, his middle name, comes from a relative who played football for the Chicago Bears - Milton Romney. The governor went by 'Billy' in kindergarten.
