In 1876, a few states sent more than one set of electoral votes.
Remember, the ruling in Bush v. Gore was, first, that using different standards for counting votes in different counties was unconstitutional, by a 7-2 vote; and then, that there was no time to fix the process before the Electoral College voted, so Florida would have to certify the results it had as of that point. (You might recall that the Democrat-controlled Florida Supreme Court had kept extending the deadline and extending the deadline.) That ruling was 5-4, and it gave Florida (and thus the presidency) to George W. Bush by 537 votes.

Read my #46.
It was the circuit court Judge N. Saul Sanders who gave Florida to Bush. The Supreme Court only stopped the unconstitutional partial recount.
