Who are some famous people who are politically conservative and don’t believe in a personal god?
Me, for some definitions of famous. (loose ones).
Penn Jillette
Do you mean fiscally conservative, socially conservative, or both?
Ayn Rand was a pretty famous conservative and also an athiest.
Karl Rove is reportedly an atheist.
Many, though certainly not all, libertarians are atheist or agnostic.
Most people view libertarianism as a particular flavor of conservatism.
Aren’t you more-or-less a libertarian, though? That’s a strain of conservatism, but I don’t think you have much truck with social conservatism.
That’s the thing, really - it’s perfectly possible to be an atheist who believes that small government and laissez-fair market policies are the best way to govern a society. I may disagree with that position, but nothing about atheism makes that a tricky position to hold.
I think it’s probably very hard to be an anti-choice homophobe, though. And while there are some secular anti-choice activists, they’re pretty rare. These positions are pretty tightly tied to religion.
Dennis Miller?
Mussolini was reputedly an atheist who sometimes played Catholic for political reasons. Quite unlike his contemporaries the sincerely Catholic Franco and Salazar. Guess who of them did not end up getting a decent Christian burial 
Also, depends on what “personal god” means. E.g. if Hitler believed in that “god” is taking care of him as part of his “destiny”, that probably counts as a “personal god”. Now how about Himmler who believed in reincarnation, was interested in Hinduism and suspected of occultism but doesn’t seem to have had a personal god of any kind? So you could classify pretty much any New Age type believer in early 20th century as this sort of “conservative” by today’s standards. I don’t think you would find many people supporting promiscuity, racial quotas and globalism in that time period, even among weird new religious movements. So pretty much everybody was “conservative”, some more than others.
George F. Will.
oh yes, how could I forget - there is always Heather McDonald Heather Mac Donald - Wikipedia . I used to like her descriptive, if not prescriptive writings, until I eventually realized that a lot of it is neocon hatchet job with some pretty transparent PC falsehoods thrown in for good measure.
Then there is also a pretty big percentage of the population of post-Maoist China. You don’t suspect Deng Xiaoping of belief in a personal god, do you?
I dunno about that. I’ve met quite a few very religious libertarians.
I’ll add William Safire to the mix.
Oh, and David Horowitz, who started his career as an agnostic, culturally Jewish lefty, and traversed the political spectrum to become an agnostic, culturally Jewish conservative.
And here’s some lists to peruse for more:
No, but I suspect him of being at least some sort of communist.
Penn & Teller
They did a BS episode on the Vatican. I might be wrong though.
They’re not conservative, per se, but I wouldn’t say they’re liberal. They’re libertarians and that does have some elements of conservative beliefs.
Other than Mussolini and Hitler, people have only mentioned Americans. But east Asia is chock full of conservatives who don’t believe in a personal god, and even northern Europe surely has a lot more than the US (and they’re more open about it).
Did William Safire ever say he wasn’t religious? I could be mixing him up with someone else, but I thought I remember him refusing to discuss his faith because it was nobody’s business but his own, and people like that are usually sincere believers.
Speaking of which, while George H. W. Bush always (well, since 1980) referred to himself as a devout Christian, he was never seen entering a church, couldn’t remember his pastor’s name, often visibly sneered when his speechwriters gave him words like “sanctity” to read (to the point where they made a list of words not to use), used the phrase “all that Christian mumbo-jumbo”, etc. He’s certainly nowhere near as religious as he pretended to be, and I suspect he doesn’t believe at all.
I’m pretty sure most of the neocon ideologues, or at least the first generation of them, are agnostic or atheist. Many are quite open about it, and most of the ones who aren’t are terrible liars. But then I’m not sure I’d call neocons “conservative” in any meaningful sense.
Here’s an interesting one: Within the Gore household, social-liberal father Al was deeply religious, while social-conservative mother Tipper never once mentioned religion to her kids except to make fun of Al.
Dennis Miller used to be an outspoken atheist but recently, on his radio show, he’s often said that he “hits his knees” (to pray) every night before bedtime. Whether that’s metaphor or literal, it doesn’t sound like something an atheist would say.
That’s not how I’d interpret “hitting one’s knees before bedtime.”
