Hank wouldn't even vote for Bush because he had a weak handshake, he would hate Trump and never vote for him. Probably would have backed Kasich in the primaries, not vote in 2016, and vote for Biden in 2020.
Honestly I think he would have passed away by now from his high-meat diet, sedentary job, high temper and health problems like the urethra if he was a real person.
Anyway probably Romney/Johnson/Jorgenson.
He'd only be 67, probably not yet. His father lived to be 71 with an even more unhealthy lifestyle and his mother was 69 when the show ended.
