Actually Cruz went down a percentage point needed and Trump went up one, but that makes little difference in the long run, just keeping the facts straight. :)
Before Wisconsin there were 867 delegates remaining. To reach 1237 delegates Trump required 56% of the remaining delegates. To reach 1237 delegates Cruz required 88% of the remaining delegates. After Wisconsin there are 825 delegates remaining. To reach 1237 delegates Trump requires 58% of the remaining delegates. To reach 1237 delegates Cruz requires 89% of the remaining delegates.
Cruz has fallen further behind.
If Cruz has 11 more Wisconsins he's out. Trump on the other hand would need 80% of remaining delegates, which is less than Cruz needs now.
