How do you think they control the vote? The ballot box is private. They can't vote in Federal elections. They aren't citizens. Are you proposing to change the Constitution?Any election. BTW, we all know what Democrats are attempting to do. They will use non-citizens voting in municipal elections as precedent for pushing for county elections, state elections and ultimately federal elections. If your argument is simply that they live there so they should have a say, that argument could be applied at every level of government.
