Good looking conservative women threaten the liberal status quo. Or, in the alternative, Republicans are the new sexy.
But seriously, the writer here is saying something I’ve noticed for a while. Republicans have always had the stereotype of being old, and, with that, unattractive. People, particularly young people, (and, I hate to say it, but even more particularly, young women) eschew the unattractive and unsexy, and gravitate towards that which they would like to emulate. Women like those described in the article were brave enough to buck that, and now they’re changing our impressions of what is attractive. Interesting.
