Cruz will not be mathematically eliminated until and unless Trump gets to 1237. There are hundreds of delegates Cruz could pick up from other non-Trump delegates and unbound delegates to get Cruz to 1237.
Cruz cannot get to 1237 ... He will be mathematically eliminated in 2 weeks ... he was practically already eliminated before last night.
Only Trump can get to 1237 ... once Cruz is mathematically eliminated his support will drop. No one wants to vote for the second place guy that cant win.
