All the pundits I have heard say that the situation is going to get

convention with, say, 1200 or 1175, delegates and they try to nominate
somebody else.

He would need the 1237 delegates to be nominated on the first
convention ballot. Otherwise; it goes to a second ballot. Delegates
become increasingly unbound after each ballot. Some delegates in PA
are not bound on the first ballot. The none-Trump candidates /
delegates could release their delegates, so Cruz has more to gain. The
convention will also be nominating a Vice President.

Abe Lincoln was nominated on the third convention ballot
