Isn’t Uncle Orson the closest thing to a conservative on that list, too? I believe he’s libertarian...
I think so. Mormon too, I believe. Sort of in the mold of a Glenn Beck type.
Gene Wolfe and Pournelle lean right, don’t know about any others besides Card.

I like Card a lot. He's pretty spot-on sometimes.
Those of you who like hard military SF who haven't already should check out John Ringo. I just finished reading the last book of the Alendata series. It rocked. if you go to Baen.com's free library, you'll find the first couple of books availsble for free download. He's fairly conservative, and generally fairly hard on the muslim hordes. If you get to the book "yellow eyes", you'll like his commentary at the end about the modern-day 'elite'.
