Trump needs to only win 18 delegates from Wisconsin to stay on target to get to 1,237 whereas Cruz needs 33. Cruz has only won only 52% of his target allocation. He is behind by A LOT. Once it becomes mathematically impossible for Cruz to get to 1,237 he should drop out just as he has called for Kasich to do. http://projects.fivethirtyeight.com/election-2016/delegate-targets/
It’s clear that this is going to be a contested convention.
