WASHINGTON, March 7 (UPI) -- Presidential candidates Hillary Clinton and Donald Trump may be leading the delegates race a month into primary season but competitors Bernie Sanders and Ted Cruz won enough over the weekend to keep both races competitive.
For Republicans, 1,237 delegates are needed out of an available 1,899 to win the party's nomination. The GOP will officially back its nominee at the Republican National Convention scheduled to begin July 28.
Clinton currently leads over Sanders with 671 pledged Democratic delegates over Sanders' 476. When including super delegates -- politicians and party leaders who can back any candidate and can change their mind at any time -- Clinton leads with 1,129 presumed delegates to Sanders' 498.
The media coverage of superdelegates has been increasingly criticized by the Sanders campaign and its supporters for allegedly making Clinton seem like the runaway winner and for painting the Sanders camp as a doomed effort.
For Democrats, the delegate results are not official until the Democratic National Convention, which is scheduled to begin July 25. The formality is due to the use of superdelegates, who can support any delegate whereas pledged delegates support the winner of a state's primary. A Democrat needs a total of 2,383 delegates out of an available 3,393 to win the party's nomination.
On Super Tuesday, Trump and Clinton -- the Republican and Democratic presidential front-runners -- both won seven out of 11 states. Cruz won three states and Sanders won four.
Cruz is second to Trump in the GOP nomination race. Sanders continues to narrow the gap with Clinton.
The month of March could decide the fate of campaigns as there are a significant number of delegates in states with upcoming contests.
For Republicans, 12 more states will hold a primary or caucus on four different dates through March 22. There are 625 remaining Republican delegates up for grabs in those elections.
For Democrats, 13 more states will hold a primary or caucus through March 26. There are 1,130 remaining Democratic delegates in those contests.
