If you’re concerned about a rightward drift, you’re not going to like many places in Europe. I also wouldn’t leave a country because of a temporary political shift. America’s left is more powerful now than it’s been in close to 100 years and it’s only growing with the next generation. If politics is the main reason you want to leave, I’d seriously encourage you to rethink things. That seems very shortsighted, especially given the political tide in Europe.
