"The reason I didn't support Trump the last time is I was afraid that he would be a divider and not a unifier -- and our best leaders historically have been unifiers, Republicans and Democrats," Kasich said. "But unfortunately, as I've watched him over the last three-and-a-half years now, he's continued to do that and I don't think the country does well when we're divided."

4. He served in the House of Representatives

Kasich was elected to the House of Representatives in 1983 and departed in 2001 after nine terms.

5. He met then-President Richard Nixon as a teen after writing a letter to him

Kasich met the late President Richard Nixon in 1970 after writing him a glowing letter while a student at Ohio State University. Kasich said he turned a five-minute meeting into a 20-minute summit, the Dayton Daily News reported.
