What if John Adams had defeated Thomas Jefferson in the 1800 Presidential Election?
I don't think it'd necessarily be changed. All the parties need to remember is to "waste" one vote on someone other than their Vice-Presidential candidate, and the Federalists certainly managed that well enough in 1800. There wasn't a crisis after the 1796 election gave us a President and Vice-President of opposing parties, because Vice-President Jefferson had so few powers that he could safely be ignored. I know parties were only just starting to develop in 1796, but I think the Vice-President's powerlessness would mean there'd be no need to change this. Again, though, it always could happen - there was no urgent need for the Twelfth Amendment iOTL, either, but it happened anyway.There wouldn't be a Twelfth Amendment, at least not for the time being. Some sort of fuckup is bound to happen and create a constitutional crisis.
True, but even simply letting it expire would quite likely have negative repercussions on civil rights, like I said.Whether or not the Sedition Act is renewed depends on how Congress turns out. IOTL, the Senate remained Federalist, while the House went to the Republicans. That outcome may or may not be the same, should Adams be re-elected.

The Republicans had planned for Burr to get one less vote for president, but one moron managed to screw it up. Unless you somehow manage to get an odd number of candidates in subsequent elections, a situation like IOTL 1800 is bound to happen at some point.
I don't think so - as I heard, they made utterly sure no one abandoned Burr to keep him from abandoning the party. Better communications and organization would help.
