All this talk of "conservative" and "liberal" sort of frames the conversation within a false duality, doesn't it? It is possible for someone to be socially liberal and fiscally conservative, for instance, or have any number of other gradients of opinion. It's geographically relative, as well, and the American political lexicon has fallen pretty far out of sync with much of the rest of the world. Amsterdam's "conservative" may well be Farm State USA's "moderate," or even "moderate with Liberal pet causes."
That said, WesDude, I don't want to pile on, but I'm not seeing where there's any ground for argument here. If someone bakes for a living, day in and day out, they're a baker. If they tell you they're a butcher because they enjoy the occasional steak, that doesn't make them a butcher-- it makes them a baker with a very distorted outlook. Or an agenda.
Some of the things Hoff Sommers has to say align fairly well with things liberals were saying 50 years ago in this country, but these days they qualify more as educated, moderate common sense. As to the rest of her opinions... I'll readily admit I don't go seeking out her stuff, but most everything I've ever seen from her is socially conservative. The Stanford Encyclopedia of Philosophy, peer-reviewed and not generally noted for its bias one way or another, classes her clearly stated views as those of a social conservative. She's won her fame championing the dismantling of the modern liberal evolutions of feminism and the generally liberal ideals informing them. Anyone with a dictionary that contains the words "liberal" and "conservative" and access to Sommers' twitter feed should be able to make the right call in a minute flat. There are shades of nuance, but she certainly leans markedly to one side.
As to her online publication history, who you publish with isn't nearly as important as the content of what you publish, and only the most irretrievably polarized talking heads only seek to preach to their own choir, so it's not unsurprising that she'd put up articles wherever she felt they were relevant. As to her being a registered Democrat, that's not saying much either. Political affiliation isn't a solid indicator of anything-- unless we're to take Zell Miller and Orson Scott Card, also both registered Democrats, as staunch textbook liberals. Not everyone toes a party line, and not everyone claims a party affiliation for purely ideological reasons.
