I've read that illegals cost tax payers about 20,000,000,000 per year in California. While it seems like a waste of money for Florida and Texas to ship illegals to northern, Democrat states, I bet it will actually force some change. It's easy to be "pro illegal" when you're in a northern state with almost no illegals.
It is only about rallying a minority in your home state to get angry enough to get out and vote in larger numbers.
