Both Gen. Wesley Clark and Sen. Joe Lieberman have decided to forgo the Iowa Caucus. That has traditionally been a key factor in determining the Presidency, but Clark and Lieberman believe they can pick up enough momentum in the Febraury 3rd contests. They also argue, particularly Lieberman, that both Iowa and New Hampshire are liberal strongholds and therefore not good at providing candidates who can challenge in the national race.
