I moved a couple states away from my family to minimize any interaction. It's not just politics. Their politics are, however, and indicator that they're not the type of people I want to associate with, so the extra distance facilitates less contact.
Of course, I moved to Iowa, which has since shifted from purplish to red. At least I'm on a blue city.
The UK vs EU and the states vs the USA is not apples to apples. As I understand it though, we're actually approaching 20 US states requiring such verification. Iowa is trying to pass something similar. This is a trend across the country, which is why I generalized the USA.
