50,000 turned out here last weekend. I'll buy you a Ruth's Chris dinner, and something stronger than Kool-Aid, if you could get 10% of that, 5,000, to show up for your position.
What you propose is to round up at least 11,000,000 people, Elian-style, and incarcerate them for a "felony." People will fight for their livelihoods, homes and families. In contrast, I find almost no-one who votes the single-issue anti-immigrant ticket. It couldn't even win an open Republican primary in a Republican congressional district.
