What is happening right now
1) Rubio knows has no chance of getting the nomination but GOP establishment wants him to stay in the race to deny Trump the delegates he needs to secure the nomination.
2) The Establishment doesnt want Trump or Cruz to win the nomination, so a brokered convention is a way to bypass the two--and Cruz knows this.
3) Kasich will be presented as the consensus compromise pick of the elites if none of the 4 get to 1,247 delegates. Notice that he hasnt taken a swipe at Donald yet, unlike suicide bomber Rubio and Ted Cruz. Also note that the RNC convention will be held in Ohio.
4) I predict Trump will win the nomination. Rubio will be his VP/Apprentice. Christie will get Attorney General, and Cruz will replace Scalia.
