I agree it makes eminent sense not to commit to the idea of giving Romney the nod in November until, at least, the GOP has given him the nod at the convention. All the discussion about possible votes for Romney in November is hypothetical unless or until Romney passes that hurdle. It could be that as part of the negotiations at the convention, Romney will be successfully leaned upon to present a VP who actually is a reasonable person. What happens eight years down the road? Even if Romney’s own ear can be bent?
The primary is over. Romney won the nomination, the rest is a formality to the already existing reality.
