Who called the caucus?

Iowa caucus results as of 1 a.m. Friday:

RESULTS: Obama 37.53; Edwards 29.88; Clinton 29.41 Huckabee 34; Romney 25; Thompson 14; McCain 13%; Paul 10%

So it appears Obama and Huckabee are the projected winers.

Iowa delivered fatal blows to the campaigns of Sen. Chris Dodd of Connecticut and Sen. Joe Biden of Delaware, and both have bailed out of the race, according to CNN.

In a nutshell, the Iowa caucus is somewhat of a primary, except it doesn't involve ballots or secret voting; instead, people visit libraries, churches, farm houses and other locations throughout the state, and will walk to the corner or space by the wall designated for the candidate of their choice.

New Hampshire will hold the nation's first primary election on Tuesday.
