Super Tuesday marks end of the phase of the campaign when primary and caucus returns are mostly interpreted in terms of momentum and what they might mean for the shape of the race, and the start of the time when delegate counts finally become meaningful. On March 1st, 865 Democratic delegates and 595 Republican delegates will be won--this does not include super delegates-as voters go to the polls or caucuses in 13 states. Thus, just over 25 percent of the GOP delegates will be determined on Super Tuesday. On the Democratic side, just over 21 percent of regular delegates will be awarded on Tuesday. The percentage is lower if superdelegates are included in the overall count.
