Just a note: There is no evidence that Routh voted for Trump except for a social media post he made and a reference he made in his book. There is no record of him voting for Trump in 2016 in either NC or HI. He voted Democrat in the 2024 NC primary.
In my mind, the bigger issue is that he wrote an open letter to Iran, begging them to kill Trump.
He flip flops on every decision so likely he did.
