Any vote for Bush/Rubio is a wasted vote. If its Bush, you abandon your base. If you’re OK with that, then do what you think is right, of course. But don’t kid yourself.
I am beginning to see a wide open republican convention. All these guys are going to be favorite son’s from their states. I don’t see any of the candidates have the nomination wrapped up after the primaries!! Remember the “winner take all” was to nominate a liberal numb skull like Mc Cain. I think Cruz will win Texas after today. Trump will win many delegates under “winner take all”. But we could very easily see a brokered convention where delegates will be bought and sold for money. ( like the old days) It will be pop corn time for sure. The “winner take all” rule is back firing badly on the establishment.
