President Joe Biden and former President Donald Trump appear headed to massive victories in states with primary elections Tuesday.

Both the Democratic president and Republican former president have already secured enough delegates to win their respective presidential nominations, and they are expected to significantly increase those delegate counts after all votes are counted Tuesday night.

Voters in Ohio, Illinois, Kansas and Arizona have both Democratic and Republican primaries, with the presidential race topping ballots. Republicans also hold a presidential primary in Florida. Democrats canceled their presidential primary in the Sunshine State, handing all of Florida’s 224 delegates to President Joe Biden.

Polls close first in Florida, at 7 p.m. eastern, followed by Ohio at 7:30 p.m. eastern, and Illinois at 7 p.m. central (8 eastern).

After victories last week in the states of Georgia, Mississippi, Washington and Hawaii, Trump raised his delegate count to 1,247, surpassing the 1,215 delegates needed to become the presumptive nominee. The nomination does not become official until the Republican National Convention in July in Milwaukee.

A total of 350 GOP delegates will be awarded after Tuesday’s primaries.

Biden reached 2,107 delegates after last week’s Democratic primaries, surpassing the 1,968 needed to secure the nomination. As with the Republican race, the Democratic nomination does not become official until the Democratic National Convention in August in Chicago.

A total of 379 delegates will be awarded after Tuesday’s Democratic primaries.
