Could I steal the election?
tl;dr It's much harder than you think. And basically to make a difference, Absolutely No.
@mcfate @corlin Are you seriously suggesting that a person who is not allowed to vote gets mad and somehow votes anyway?
In 1998 Florida purged up to 100,000 legitimate Black voters. In 2000, its 4 electoral votes decided the presidential election. "An investigation by the United States Commission on Civil Rights revealed 'an extraordinarily high and inexcusable level of disenfranchisement,' primarily of Democratic African American voters."
