After business mogul Donald Trump was declared the winner of the Indiana Republican presidential primary, Ohio Gov. John Kasich reminded supporters that, yes, despite only winning one state so far, he is still in this thing.

Kasich's campaign posted a note to his Facebook page outlining what's next, saying the loss in Indiana "would not alter" the GOP presidential hopeful's plans.

"Gov. Kasich will remain in the race unless a candidate reaches 1,237 bound delegates before the Convention," the note said.

With Tuesday's win, Trump is closing in on the GOP nomination, securing his already large lead in the delegate race.

UPDATE 5/4/16: Kasich will suspend his campaign Wednesday evening, according to reports.
