"You have only one choice. One choice that will stop the Clinton political machine," begins the 60-second TV spot. "Don't be fooled.

"John Kasich will win the convention, and he'll defeat Hillary Clinton in the fall,” it continues.

The ad comes just weeks before the state's April 19 primary, in which Kasich and his rivals will battle it out for a share of the 95 delegates up for grabs. 

Kasich, who hasn't won a primary since his home state of Ohio in March, is poised to take second place in the state, with polling averages showing him passing Cruz to gain 22 percent of the vote.  

Trump, a native New Yorker, is expected to blow out his rivals, with 53 percent support among GOP voters, according to a RealClearPolitics average of polls.

Kasich has repeatedly said he's counting on a contested convention to win the party's nomination and thinks delegates on subsequent ballots will switch to his side and abandon Trump and Cruz. 

Polls do show Kasich could easily beat Clinton in a general election.
