Voting in Florida, North Carolina, Ohio, Illinois and Missouri Tuesday could mean make or break races for Republican candidates Ohio Gov. John Kasich and Florida Sen. Marco Rubio, who are polling at the bottom of the pack. The votes present the opportunity to pick up a significant share of delegates in the 2016 nomination race.

On the Republican side, Florida has 99 delegates up for grabs, North Carolina has 72, followed by Illinois with 69, Ohio with 66 and Missouri with 52. Both the Democratic and Republican candidates have the opportunity to pick up almost 15 percent of all delegates in the race Tuesday as contenders strive to reach the mark needed for the nomination.

For Kasich and Rubio, winning their home states will be key to continuing their campaigns, with businessman Donald Trump holding a commanding lead in the polls. Tuesday evening’s votes make up approximately 15 percent of the delegates awarded, with a winner-take-all system in place in Florida and Ohio. Illinois plays by a winner-take-most system.

Trump enters Tuesday evening with the most delegates. He had 469, followed by Texas Sen. Ted Cruz with 370, Rubio with 163 and Kasich with 63. To gain the nomination, 1,237 delegates are needed. Despite Tuesday’s results, Rubio has promised to remain in the race.

For Democrats, approximately 14 percent of delegates are at stake Tuesday evening, with almost 700 delegates. On the Democratic side, Florida leads with 214 delegates followed by Illinois with 156. Ohio has 143 delegates, North Carolina has 107 and Missouri ends the count with 71. Clinton’s campaign has expressed confidence going into the vote, ordering Cuban food at its headquarters in Florida with polls ahead of the vote showing the former secretary of state in the lead.

The delegate count on the Democratic side is much wider, with Clinton in a commanding lead with 1,235 delegates versus Sanders with 580. For the nomination, 2,383 delegates are needed.
