John Kasich on Presidential Election: 'This Is a Long, Long Race'

ABC News' George Stephanopoulos talked to John Kasich on "GMA" this morning.

"Everybody always underestimates me," he added.

Kasich's home state of Ohio is a crucial winner-takes-all delegate prize. Ohio residents do not cast their votes until mid-March.

"I think it's a sad situation," he said. "I'm not going to get diverted by it."

"The light really does overcome the darkness," he continued.
