Interactive Primary Map

Mark your calendars, politicos: Feb. 5, 2008 could be a long night.

U.S. News & World Report's Dan Gilgoff takes a look at the bevy of states that are considering moving--or have already moved--their state's primary to the first Tuesday in February of 2008. If every state currently pondering the move were to do so, 24 states could select their candidate for the presidency that day.

Included in Dan's story is an interactive map developed by U.S. News with information on each state.
