Yeah, if you count libertarians as conservatives, you've definitely got Ditko and Bagge (who does excellent cartoons for "Reason"), and possibly Miller and Sim.
You might even have Garth Ennis. Some of his "Preacher" stuff seems Libertarian or even Conservative to me, once you get past the graphic sex and ultra violence.
Is Bagge a Libertarian? I hadn't heard. I also haven't heard Ditko called a Libertarian (although he is supposed to be an Ayn Rand philosopher). Bagges' interpretation of Ditko lead at least one critic to say that Ditko got Rand wrong and was a Reaganite.
Generally people just say that he is a "conservative".
Harvey Kurtzman and Al Capp were conservative on some issues (certainly when the radical elements of the Democrat party took to the streets and armories in the 1960s). The left doesn't like the "conservative" era work from Kurtzman or Capp (although both may actually be Democrats).
Because of media bias, what they term "conservative" may just be anything to the right of Marxism.
I would be wary of some people who call themselves Libertarians too, Bill Maher thinks he's a libertarian.
