There’s also a ton targeting Latinos, though it is often overlooked as it’s frequently in Spanish. It’s also not discussed ever, but I am quite convinced that left-of-liberals are being heavily targeted.

As for the why, because they’re very online groups, often polarized, and that tend to vote a particular way but don’t necessarily identify with the way they vote. Moderate-minded people who identify heavily as democrats or republicans aren’t going to change their views as easily. Those groups also have plenty of valid anxieties about the political system, and that can be exploited.
