Trump is not mathematically eliminated. He has a challenge, but there are still enough delegates available that he can win.
If Cruz wins every single delegate from here on out - 100% of them - he still comes up short of 1237. There is no way he can win.
Trump can still win - Cruz cannot.
Not yet. But should he be mathematically eliminated, should he then withdraw from the race?
That’s not counting all of the unbound delegates. There are over 100 of them I think, mostly from 3 states. All of them will have to pick someone to back on the first ballot. I’m not totally sure if the delegate counts that are out there have factored in any of them who might’ve verbally pledged, but I think not with most.
The idea that someone should drop out if they can’t win on the first ballot is a backdoor way of changing the rules of the convention. Why are there rules about how a 2nd ballot is handled if the candidates are all going to agree to never allow it to happen by dropping out?
No one is truly mathematically eliminated until one candidate gets 1237 bound delegates or other convention rules preclude them from entering their name into nomination.
