Conservatives will think the same about any public figure who’s any degree to the left. It’s just a human cognitive bias at play that we’re all susceptible to. If you think someone is a shitty person, that’s going to cause you to overemphasize whatever physical features you find negative about them. The danger of this is that you might in turn start using those negative features as an unreliable heuristic to judge the character of other people before you even get to really know them.

The different fashion/makeup trends among people across the political spectrum can also come into play similarly.

There are conventionally unattractive public figures on the left too, but if you know beforehand that they’re on your “team”, you probably won’t even take particular notice to these “defects”. In some mirror universe where MTG was as far left as AOC, you’d probably wouldn’t think she looked “evil”.
