Answer:
The only constitutional change that resulted from the election of 1800 was the twelfth amendment requiring separate electoral votes for president and vice president.
Step-by-step explanation:
Democratic-Republican Thomas Jefferson defeated Federalist John Adams by a margin of seventy-three to sixty-five electoral votes in the presidential election of 1800. With the votes tied, the election was thrown to the House of Representatives as required by Article II, Section 1 of the U.S. Constitution.
