If no one at 1237 Cruz wins in the second round. Trump still only gets about 1/3 of primary voters support. He is not consolidating the party and cannot. He is old and has no control over his mouth or hands. He is one hair to the right of Hill and they are probably tied on lying.
It really doesn’t matter. If a brokered convention nominates anyone other that Trump, you need to be concerned with Hillary’s VP, because they will be moving into the White House. Don’t worry the GOPe will continue to root in the government graft pig pen. But I will be staying home if the GOPe steals the nomination.
