Constitutional Residence"According to the Constitution, electors must vote for at least one candidate from a state other than their own. This is why political parties usually select presidential and vice presidential candidates from different states. If candidates on one ticket were from the same state, that state's electors could not vote for the ticket.
Just before he was nominated as the Republican candidate for vice president in 2000, Dick Cheney owned a home in Texas. Before the election he changed his legal residence to Wyoming, his birth state, which he had represented in Congress. Some Texas voters questioned the move and filed suit over the legitimacy of giving Texas' electoral votes to Bush, who had been Texas governor, and Cheney. Cheney's residence in Wyoming was ruled satisfactory in court."
