My attitude towards Keyes is based on the fact that he often appears to be slightly deranged.
Some people dote on that fire-and-brimstone old-time-religion speechifying.
Most people are hugely put off by it.
We'll see. Personally, I abhor dilettantes who snipe away from the sidelines, and spend too much time worrying about their image to actually accomplish anything. So it's all subjective. I would say to those who don't like Dr Keyes style, 'fine. Have your little shot at him, and move on. If you're going to stalk the threads, dismay his supporters, and undermine the morale of his campaign, then at least be honest- it's not just his style, you dislike.'
