I heard that earlier on Fox as well - he’s apparently being saying this for a while (reminiscent of Dr. Ben in Iowa if you ask me).

Ted Cruz Needs Indiana to Be Like Wisconsin
The state has a favorable profile for the senator, but he hasn’t won over local officials or media
FRANKLIN, Ind.—For Ted Cruz to stop Donald Trump from seizing the Republican presidential nomination, he must replicate his Wisconsin victory in Indiana, another Midwestern state with similar demographics and population.
But even with Ohio Gov. John Kasich’s ceding Indiana to him as part of a nonaggression pact, it’s a tall hurdle.
Mr. Cruz has none of the structural advantages he enjoyed in Wisconsin, where the GOP governor and conservative talk-radio hosts backed him to block Mr. Trump. Indiana’s most respected Republican voices have stayed neutral, and local conservative media haven’t picked sides ahead of the May 3 vote.
“For a Cruz-Kasich axis to pay off, they will need to find a credible voice that has pledged for Kasich and urges others to vote for Cruz,” said John Hammond, an Indianapolis attorney and member of the Republican National Committee who hasn’t endorsed in the race but has expressed deep concerns about Mr. Trump.
So far, such a voice hasn’t materialized.
