If Cruz has 11 more Wisconsins, Donald Trump would also be "eliminated", because he could not get to 1237 either.
In fact, Donald Trump would be behind, at that point.
Not even close to reality.
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.
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.
