The arrogant one is Cruzie, who thinks that he can walk out if a brokered convention with a nomination. So he is either arrogant or stupid.
You need a dictionary.
Trump is the definition of arrogant.
There will be no “brokered” convention.
Nobody will have the REQUIRED 1237 on the first ballot.
There will be a second ballot, and many bound delegates will be released, and Cruz will win on that second ballot.
There is nothing “brokered” about that process.
