This should make the Trump team squirm. Trump was polled as walking away from this, and not only has he lost states, he's won many by a far less margin than predicted.
If Kasich is ahead, he could be WAY ahead.
What the Trumpers don't want to hear is that if Trump loses OH, it becomes very very hard for him to win the nomination outright. As it is now, he needs to get all the WTA states and 64% of the total remaining delegates to get over the hump.
