Sen. Ken Salazar on Monday met with three other Democratic senators who are uncommitted superdelegates, but he insisted afterward that he hadn't made up his mind whether to back Barack Obama or Hillary Rodham Clinton.So what's Mark Udall's reason for holding out on Barack Obama?
He and three other Colorado superdelegates — Congressmen John Salazar and Mark Udall and Gov. Bill Ritter — have yet to publicly back either candidate. Pressure on the uncommitted delegates is mounting as Democratic Party leaders are eager to begin trying to unify the Clinton and Obama camps.
Rep. Udall's office could not be reached for comment.Meanwhile, the Udall Watch timer counts down.
