This would be the outcome of a brokered convention. Anyone thinking this would be good thing is delusional.
A brokered convention is neither anything new nor anything to particularly fear. But the point is that will have to happen if no one wins the nomination in the primaries which is appearing very likely.
It would mean, however, that Mitt could not win it outright and probably not at all if he doesn’t. So that, to me, is a good thing. I doubt that a brokered convention would turn to Mitt.
