It's very clear, considering that the Governor endorsed him/found it politically expedient to endorse him, and that anti-Trump forces have been outspending the Trumpists in Indiana (which wasn't the case in the Mid-Atlantic), that Cruz is indeed closing the gap. But, as the article itself states: with 48 hours to go, he still seems to be down in a must-win state.
Bobby Knight is a far more valuable endorsement to have than that of big money people that have been out-spending Trump everywhere thus far and Mike Pence giving the most apathetic endorsement I've ever seen.
