There were numerous investigations into the vote count in Florida, some showed Bush won, some showed Gore won. But the fact is, the Florida vote was only ever about the Electoral College.

Gore won the nationwide popular vote--and the popular vote count has never been in question.

I don't know how many other presidents, if any, have ever won the Electoral College vote, and lost the national popular vote before. But I'm sure it would be easy enough to find out.

I'm fairly certain there have been other instances where the Supreme Court has been involved in the presidential vote, but offhand, I don't know what they are. Nonetheless, the *stopping* of the vote count by the Supreme Court is, if I recall correctly, unprecedented.
