Baen isn't really right-wing so much as they want action-heavy books and don't care about the politics. Baen does action, Tor typically does more philosophical stuff. Now, Jim Baen, personally, was a bit of an old-school right-libertarian (it's rumored that Tom Kratman's legendarily bad Evil Hillary fanfic State of Disobedience was JB's price for hiring on Kratman long-term), but he still published a lot of Eric Flint stuff, ranging from the Belisarius saga (which goes into great detail about how preposterously masculine and badass the Indian and African protagonists are (particularly the Rajput warlord who is essentially a Dwayne Johnson character minus the quips, and the East African hunter/philosopher/teacher who is simultaneously strong enough to throw a spear through two dudes to injure the guy behind them, and smart enough to argue at par with the era's most celebrated philosophers), well above and beyond the Greek protagonists, and is essentially an extended author tract on why racism is bad, and feudalism, and totalitarianism, etc. etc....), to 1632's "socialist revolutionaries rally the People to defeat the treacherous reactionary rebellion while MANLY AMERICAN UNION MEN fight for FREEDOM AND LABOR across Europe and humiliate the greatest military minds of the era with their courage, tenacity, and tactical brilliance" plotline (and keep in mind, this is toned down from the first draft of 1632, where Flint wanted to guillotine basically all of Europe's royalty and most of the nobility and replace them with a socialist revolutionary society built by Gretchen "Communist McDonald's" Richter), to the later Honor Harrington books, where Flint's Mary Sue self-insert runs around humiliating the evil slaver empire in the name of leftist principles.
The general principle of Baen seems to be: You do your politics, we don't give a crap so long as it sells. And frankly, I can tolerate them publishing scum like Kratman if it means they keep that free library thing going. That free library is a great thing, and Tor's ebook of the month thing just doesn't compare.
Just skip anything with Kratman's name on it, or Correia's for that matter. Kratman's a Nazi symapthizer and Correia's just a prick. Might want to avoid Michael Z Williamson, too, Freehold is like if Atlas Shrugged were also Atlanta Nights.
