Donald Trump holds leads over his GOP rivals in key primary states — including Marco Rubio’s home state of Florida, a poll released Monday shows.

Ahead of the March 15 Florida primary, Trump leads Rubio 38 to 30 percent, with Ted Cruz at 17 percent and John Kasich at 10 percent, according to Monmouth University data.

Trump has a 27-point lead over Cruz in New York, Monmouth said. New York’s primary is April 19.
