Updated June 02, 2008For the first time since 1928, in 2008 neither a sitting President nor Vice President will be a candidate for nomination to the Presidency. (Harry Truman briefly ran for the nomination, then bowed out after New Hampshire.) Both parties have open races, and the early announcements of contention are testimony to this. In addition, the states have joined the chorus and, as a result, Super Tuesday has moved from March to February.
