Are you sure they aren’t adding the remaining delegates to Cruz’s bar? I watched it a couple of times and they said nothing about adding Kasich’s current delegate count to Cruz’s and you get more than Donald.
Can’t speak to your interpretative skills, but their intention is clear to most viewers. It is to make it seem that Kasich’s 143 delegates added to Cruz’s 465 delegates would put Cruz on top of Trump’s 739 delegates. Sorry, it doesn’t add up. They started out with real numbers, rearranged those bars which represented those specific numbers to a bar amount that exceeds Trump’s.
It’s a slick add that’s inherently dishonest. Trump just called them out on it. The laugh’s on them.
