Oh, spare me. This is uncharted territory with the possibility of a brokered convention and with the anti-establishment massively leading the vote totals.
This groundwork has been laid for weeks. Rafael Cruz is the GOPe's hail mary to prevent Trump from getting 1,237 and to install arcane, hypocritical rules that will give other candidates a chance at the nomination even though all of them will have even less delegates and definitely less popular vote totals than Trump.
If Rafael Cruz is the conservative that his naive supporters think he is, he will withdraw from the race and return to the Senate to stop the rest of Obama's agenda.
