He doesn’t have over 50% of the delegates now. Rubio and Cruz combined have more than Trump. With the closed primaries coming up, it is unlikely he will hit the number of delegates needed. With a good chance of Rule 40 being changed before the convention, I wouldn’t worry about the 8 states at all.
