Hi snugs! I think this is why he did not seriously run. He realizes the right will not support him other than being a bit player to support conservatives. It was a PR move to appoint him as Secretary of State, and that's the closest he will ever get to the Oval Office. It's the same fate McCain has, although in McCain's case he does learn from past mistakes.
I'm not so sure. IIRC, McCain has hired Armitage onto his team.
