However, if the rules allowed for all delegates whose candidate is no longer running to become ‘ubound’ - I could get behind that. Saves time and money.
The rules exist for good reason, and does allowing rules to change.
It's also a good idea for the party to control - to some extent - who is nominated. I know that's going to sound horrible to some right now but if a true leftist ran as a republican (think somewhere to the left of kasich) and masses of democrats flocked to the GOP in every liberal state they could take over the party. That would be very bad.
Generally speaking, I think the rules should stay in place until after the nomination is made.
Rules changes should be in place at least six months before the first vote is cast. (By caucus or direct vote). If the campaign can't get it's act together in six months they'll likely be a disaster in office where you don't get six months to learn how legislation works.
The delegates make the rules though, so how could you set the rules before the first vote is cast? The only thing we could do do is set them 4 years in advance, which means we’d be bound to Romney’s rules now. Or let the entrenched GOP establishment set the rules without control by candidates.
In other words, exactly what's happening now.
