You have to factor in the other delegates - the Rubio, K. Etc. - Jim
The first round may result in no winner, so second round, some delegates will move. What portion go Trump. What portion go Cruz.
Kaisich and Rubio are out but potential King makers.
So neither Trump or Cruz can be mathematically eliminated at fhis stage. They are both in he final round.
Yes. No one is "mathematically eliminated" until someone gets to 1237.
