Romney, the 2012 GOP presidential nominee, announced Friday that he will be voting for Cruz in Utah’s caucuses this week.

But a new ad by Kasich shows Romney supporting the Ohio governor at campaign events last week.

“Unlike the other people running, he has a real track record. If you want to see that balanced budget, if you want to get rid of ObamaCare, we’ve got to turn out and make sure we send a signal loud and clear,” Romney says in the clip.

“America is counting on you. A great governor of a great state, John Kasich.”

“At this stage, the only way we can reach an open convention is for Senator Cruz to be successful in as many of the remaining nominating elections as possible,” Romney said. “A vote for Governor Kasich in future contests makes it extremely likely that Trumpism would prevail.”

Kasich responded Friday with a statement that accused Romney of falling victim to bad political advice.

“The fact is the establishment has gotten it wrong this entire primary and it is unfortunate to see that Mitt Romney is getting bad political advice,” John Weaver, chief strategist for Kasich for America, said.
