Just for the record, I am taking as campaigning anything that states a reason to vote for or vote against one or more candidates. If True Democrat had confined himself to "This was a tough choice." I would not have considered it as campaigning, but he continued on to give a reason to vote against Gabu with "I just think we should give someone else a chance." and thus crossed the threshold into the realm of what constitutes campaigning in my opinion.
I agree that it is campaigning, but I also believe his vote shouldn't have been invalidated before the vote was certified.
