American voters do not elect the President directly. They vote for members of the Electoral College. Those members of the electoral college vote on the President. Popular voting numbers are meaningless. Al Gore won the popular vote but George Bush was selected by the electoral college and he became President. It’s Civics 101.
You can vote for whomsoever you wish and the Electoral College will select whomsoever it wishes. It’s just that simple. Thanks, Founding Fathers, for ensuring the power of the Oligarchy no matter what the populace wants.
