The reason is that Seamus is a conservative but not a republican. His true political party is Conservative Libertarian and he has gone against a couple conservative stuff before. One is war criminals are guilty before proven innocent while it’s not really conservative he painted it as such with a Democrat talking about how all rape trials should be considered guilty before proven innocent and a republican talking about how war criminal trials are guilty before proven innocent. He also has the straw men series which makes fun of republicans and democrats.
