From what I've read he wasn't really a Republican exactly, but more of an independent with idiosyncratic beliefs who supported Trump and then became disillusioned with him. I don't think he ever identified as a Republican, even though he was previously a Trump supporter.
So… basically a republican? That’s how they all describe themselves… they’re all independent thinkers who happen to align with the most popular racist. You know by chance…
Could have been one of them newfangled Libertarians, who align 100% with Republicans, but are independent thinkers because they consume "alt" media instead of Fox News.
They might even be mildly against Trump because they're such independent thinkers (translation: contrarian), and may vote 3rd party. That way all of the worlds problems are someone else's fault.
