Does that mean your man will drop out when he no longer can reach that magic number? Oh no, because he plans to win it in a contested convention since that is his only real hope of winning it, and has been for quite some time.
I'll repeat the long standing rule.
The winner of the nomination needs to have a majority of the delegates, in this case 1237 delegates.
No he has been pinning all of his hopes for more than a month on keeping Donald from 1,237 and entering into the convention with hopes of maneuvering a 2nd or 3rd vote win. Which is why he is now cozying up to the GOPe.
