I don't know this for fact but I would guess they flew people from around the world to the Mexican boarder. There was a utube post about it that was deleted. So just sit back and let the polticians manipulate us so they can win an election. I don't get how they ever loose. They have about 20 million illegals voting, they sign them up after they enter. They get all the Teachers, state, local employees and all of the welfare/social assistance votes. the USA's future is communism like Kruschev said.
