By the time the people are angry enough to force a political shift, they simpily will not just stop at electing people who are anti globalist, they will elect those who are full on Socialist. The Open Border/Free Trade lobby will not fully understand what hit them in a few years.
Actually, you should check out Carl Marx's speach PRO Free trade. He saw it as a great way to destroy national identities and central governments and to create a huge poor worker base and a small super rich elite that would be easy to destroy for the future revolution. So, Free Traitors are either socialists/marxists or useful idiots.
