He switched over to the other side 5 years ago at least overtly. He may not be a full fledged dim but he’s close.
The specific term doesn't actually matter. The Dims and RINOs are all part of the Democrat Party Cabal (along with Soros, violent BLM/Antifa, CCP, Big Tech, MSM, Corporate America CEOs, academia, etc.). As you're probably aware, all of those groups worked hand-in-hand in 2020 to steal the election for puppet "Sleepy Joe" and Laughing Kamala. And even though they stole the 2020 election, they're now even more hateful, spiteful, and bitter.
He was never on our side.
We were conned by lots of smart people to vote for this idiot.
