Today the Candidates, Tomorrow the Voters

Super Tuesday or Tsunami Tuesday amounts to a national primary, the first of its kind in American history. With just hours remaining before the biggest caucus and primary day in American history, presidential candidates are racing around the country. In both parties, they're competing for almost half the convention delegates needed for nomination, spread from big blue states to numerous red ones. We touch down in the Far West, Southwest, Midwest, the Deep South and the East Coast and hear how the war, the economy, healthcare and immigration are helping or hurting Democrats and Republicans. Will Super Tuesday be decisive for either party?
