On Monday, Mitt Romney visited Ohio to urge GOP voters to cast their ballots for John Kasich. Appearing at an airplane museum, Romney told the crowd that to vote for Kasich, though both aides for Romney and Kasich both asserted that the speechmaking did not constitute an official endorsement.

Speaking of Kasich, Romney told reporters, “He’s gonna come in and be positive. He’s gonna talk about me. I don’t expect he’s gonna be trashing anybody. We don’t want that.” Last week Romney recorded robocalls for the Kasich and Rubio campaigns, according to the Wall Street Journal.

Romney is following the path he himself laid out for GOP voters who want to stop Donald Trump from getting the GOP nomination. In early March, speaking at the University of Utah, Romney stated:

The rules of political history have pretty much all been shredded during this campaign. If the other candidates can find common ground. I believe we can nominate a person who can win the general election and who will represent the values and policies of conservatism. Given the current delegate selection process, this means that I would vote for Marco Rubio in Florida, for John Kasich in Ohio, and for Ted Cruz or whichever one of the other two contenders has the best chance of beating Mr. Trump in a given state.

At Westerville Central High School Monday night, Romney exhorted the crowd, “I want to make sure you guys will do the right thing tomorrow. You’ve got to turn out tomorrow and make sure we send a signal loud and clear that a man with integrity, a man with a clear track record, a man who has shown what he would do to get a state to turn around, will do the same thing for the country.”

Meanwhile, Trump was lying about Kasich on Twitter:

As CNN reported, "Neither tweet is factually accurate. Kasich is still on the ballot, and the signatures his campaign submitted to get onto that ballot were certified by the Pennsylvania secretary of state." CNN reported that Rob Nichols, a spokesman for Kasich's campaign, stated, "Trump's dishonest tweets and robocalls means his team either knows nothing about Pennsylvania election law or he's just scared to death we're going to beat him."
