Don't you get it? The EVIL plan is a long con. They were very patient and they've come to harvest the crop of their work. They started to get lax on immigration 20 years ago+, hoping for anchor babies and others to grow and multiply. When they were still seedlings, they'd feign opposition to them, but not do anything because it's such a small problem. And now, their crop has grown and they've come to collect the votes.

They never expected that to backfire.
