I was fooled by his 2008 GOP nomination for President and his continual re-election as AZ Senator.
I know that you know very well what I mean. You are being coy. As far as his incredibly incompetent run for President, as well as his disastrous pick for VP, he virtually locked the election for Obama. I went to one of his rallies. He banned anyone from saying Obama's middle name "Hussein" and spent several minutes of his own campaign talking about what a Great guy Obama is. Also, he put Palin in a virtual lock-box even though she was generating momentum at the time, and tightly reined in anything that she may say or anywhere she wanted to go.
In short, whether through incompetence or deliberate thought he basically gave the election to Obama.
In terms of being elected as a Republican Senator in AZ, these are the same people who voted for Flake and for Sinema. So, it seems obvious at least to me, that AZ voters are unable to tell the difference between a Republican or a Democrat.
However, I respect your opinion. I'm not trying to convince you of anything. If you say McCain was a loyal Republican, then that's fine with me. I disagree, but whatever.
