That's correct. If he had the case and got a donation, you'd have a point. He was running unopposed and didn't need the money. As it is, you've got nothing but unfounded speculation -- which is typical for you.
Read what I said, for pity sake. It's in plain English. There was nothing to gain by a contribution because the case wasn't before Greer at the time.
People as a rule don't spend money unless there's something to gain by it. One may therefore assume Felos and Bushnell had something to gain by making contributions to Greer. That is why it had the reek of impropriety -- at least while their litigation was before his court.
