Update: Tough Clinton questioner signs up with Edwards

NASHUA, N.H. -- The man who found his way into several national news accounts for his question to Hillary Clinton at her first town hall meeting in New Hampshire whether she -- "right here, right now" -- would say her 2002 Iraq vote was a mistake, has signed up with John Edwards.

Roger Tilton of Nashua attended a town hall meeting for Edwards at an elementary school Friday.

As the event began Tilton, for the first time, signed up as a supporter of Edwards on a clipboard in the hallway.

Tilton said even though he had two daughters and would like to support Clinton, he meant what he said in his question in January, that he could not even hear what else she had to say until she admitted her vote was a mistake.

Tilton said he thought Edwards was "authentic" because he has said his vote was a mistake.
