OK, so here’s the plan. Take over the driving of any busload of SIEU outsiders and drive them around town until the polls close. That way, they can’t vote illegally - at least not as long as you’re driving their bus.
I would seriously consider immobilizing any out-of-state licensed cars, vans, or busses that show up at any polling places. They can’t cheat if they can’t get from polling place to polling place.
I heard a couple of truckers calling in to Right-Wing Hate Radio just after the election in 2008, reporting the highways out of New York loaded with cars returning to Ohio, Illinois, Arkansas, Indiana, etc.
