Honestly the guy’s last name sounds like a knockoff of Gomer. And he shares his first name with the orangutan from the Jungle Book. If you were writing a novel and needed a name for a character who was a rube southern politician, you’d reject Louie Gohmert outright as sounding way too cliche.
I should also add that I think it’s hilarious that his name is close to Gomer without actually being Gomer, as it makes it that much funnier when somebody slips up and calls him Gomer.
