Because, frankly? A country that is down with electing somebody who overtly panders to white supremacists is not a country I really want to be in. A country that elects somebody who thinks electrocuting teenagers to cure homosexuality is not a country I really want to be in. I don't need to see what they will do to know what they have done.
I don't intend to move stupidly, and I don't intend to unless I can better my situation--but I wasn't even considering it yesterday, and I am now.
