Not surprising but you have mischaracterized the Right's opinion of Comey. It doesn't amount to "What a great ally, and his decisions and actions have been super wonderful!"
He blasted Clinton but then let her skate. It was Dems singing his fulsome praise after that, not Republicans.
He reopened the investigation and got slaughtered by Dems, but few Repubs thought it was going to go anywhere other than where it went, just not that quickly.
I don't have the slightest idea what was going through his head, but I don't think it was all good and I hope someday we find out. He, Loretta Lynch, Obama, and of course the Clintons were responsible for making America seem like a Banana Republic. For his contribution to that depressing state of affairs, he should be fired, but that would only contribute to the Banana Republic meme if the lame duck current president was seen to deliver political retribution.
I don't think Obama should or will fire him and I hope Trump doesn't either. His credibility is shot and I think it will eventually lead to his resignation.
Unless Obama pardons Clinton (which will be all the proof anyone should need that she is a corrupt crook) the Foundation investigation will likely continue into Trump's term. I can't imagine anyone buying any conclusion he draws on that one unless it is 100% what they want to hear.
For a guy who had such a Sterling reputation, he sure found a way to tarnish it entirely. Almost a tragic figure.
