Update: This was supposed to run Friday but, for some reason, never managed to get scheduled. Since then, we've heard conspiracy theories that the GOP establishment is actually eyeing Romney as the beneficiary of a convention floor battle. The elites would probably love that, but I don't buy it. Even the RNC is smart enough to know that running Romney - again - will result in yet another loss. If a brokered convention is in the offing, Romney will help set the stage but Rubio is still the best bet to get the nod.
For a moment, let's set aside the question of whether Trump can win the general or not.
