Hugh, you’re (a) a smart man and (b) as relevant or more so to this discussion, a Californian. You have to know that if you stiff the million-plus Republican primary voters here alone who just picked Trump running away over Kasich and Cruz, it will have consequences both for the California GOP and the national party, none of them good. I already went no-party-pref last year because I saw the mess coming. I can tell you that if you guys succeed in doing this, I will never come back and I will never vote for another Republican. Never. Ever. Ever. Have fun storming the castle.
The evidence suggests otherwise. Blocking Trump from the nomination will fatally taint whoever might replace him as the nominee. There's no path to a victory.
Perhaps if they asked themselves how they might explain their betrayal to the millions who voted for Trump...they would stop this folly.
