Delegates are the name of the game in the Super Tuesday primaries taking place in 11 states - or how many delegates the contenders can tot up in one fell swoop for their party nominations this summer as candidates in the November elections for the next US president. The leading challengers aiming for the top slot are Donald Trump, who has turned the Republican race on its head, and Hillary Clinton, who recently pulled ahead off her Democratic rival, Bernie Sanders.

Trump hopes to grab 595 delegates this Tuesday (1,237 needed to win the Republican nomination) with Senators Marco Rubio and Ted Cruz breathing down his neck. Clinton is fighting for 1,004 delegates (out of a majority of 2,383 needed to win, although this party also has “super delegates” who may tip the scales).
The hopefuls who come in at second or third place in both parties may decide to hang until the winner-takes-all race on March 15.
