Romney supporters agree.  Cheating is silly.

Oh, you silly Michigan Republicans. Yes, I voted in the primary. Yes, I voted for Mitt Romney. Yes, I want to see Romney prevail in the delegate count. No, I don't want Saul Anuzis to put his thumb on the scale. Give Santorum his stupid delegate and be done with it. Intentions aside, retroactively "interpreting" the rules to favor a favored candidate smacks of dishonesty even if such interpretation is valid and squeaky clean. The appearance of impropriety is what matters, not the actuality of impropriety.

Note the lack of a waiver (still waiting on ANY repudiation folks!) for approval of the change, prior to it happening, issued by the RNC.

Thumb on the scale indeed.
