Your frustration with the McCain/Huckabee backroom deal is understandable. But there cannot be a forced runoff between McCain and Romney, no matter how many people demanded it. Elections are held under the various state election laws, and they are what they are. No runoffs are possible in this case.
Well, I know that in Colorado, the delegates haven’t actually been chosen, yet. That happens in August, I think. This is where we might be able to demand a runoff.
