A reader writes: What perplexes center-left types like myself . . . who are often sympathetic to Libertarian attitudes on cultural questions is why most Libertarians privilege issues of tax policy and economic regulation on which they are more closely aligned with Republicans over issues of privacy (sexual and otherwise) and free expression
About 15 years ago, I heard a pretty good answer to this question, from a fellow named Charles Fuller. As I recall, he put it more or less this way, of course as a broad generalization: The Republicans want to control my sex life, and the Democrats want to control my economic life; these days -- perhaps not always, but these days -- it's much harder for the government to control my sex life than my economic life, so the Democrats are the bigger threat.
Two quotes from PJ O'Rourke can help with the analysis:
"Republican politicians are better than Democrat politicians because they don't support gun control so if you don't like them you can just shoot them."
[The following is not a quote but a restatement, I can't remember the quote.]
"Republicans want to control my sex and drugs while the Democrats want to control my money which means that they want to control my whole life." [Since money touches on all of life.]
I would also deny your correspondent's claim that the Reps are worse on Free Expressions than the Dems. The Reps have been much friendlier to Free Expression in conflicts over broadcasting deregulation, commercial speech liberalization, corporate political speech, speech on campus, campaign finance, union dues/forced political contributions, and even street picketing (abortion clinics) than have the Dems. And the Republican dominated Supremes are more liberal than the Warren Court on Free Expression.
