As a former Democrat myself, I think it is possible that he “saw the light” or at least parts of it some time ago. The question is what one is converting to? I like the conservatism in the Republican Party, but mistrust the RINO cronyism and the neo-con contingent. Maybe this aspect made this guy squeamish too. But going independent as an office holder cuts you off from money and support. He had some thinking to do.
I’m just saying I welcome this man who is trying to serve his city. I have no problem cutting him some slack for how long it took him.
