The race remains too close to call in Ohio between Trump and Kasich. A winner-take-all state, the winner will receive all of Ohio’s delegates, no matter how narrow the victory.
Florida, Missouri, and Illinois are also holding primaries elections, with polls closing later in the evening. Trump is expected to sweep all three, including the home state of rival Florida Senator Marco Rubio.
Earlier on Tuesday, Trump also won the Northern Mariana Islands Caucus, taking 9 delegates.
The next Republican race occurs Tuesday, March 22, when Arizona and Utah hold primaries, and American Samoa holds a convention.
