We can't afford to give Romney MORE delegates after North Dakota, Colorado, and Wyoming.
I don't see why we didn't vote on unbinding them even if we may have lost. Seems like whoever agreed to this lacks any common sense.
Not voting on it also seems like a plan to give Romney the nomination.
edit: also this puts the delegates in the position of not knowing for sure whether they will get replaced by alternates at the convention if they abstain. So basically if they think it's borderline as to Romney not having the the 1166 or whatever number it is, then they might try to abstain otherwise if he has sealed the deal, they probably vote Romney since they don't want to be removed.
