Question: What is different in comparison between the 1800 electoral system and the system in place in 2004?
Sentence: This was the first time in U.S. history that an elector had cast a vote for the same person to be both president and vice president; another faithless elector in the 1800 election had voted twice for Aaron Burr, but under that electoral system only votes for the president's position were cast, with the runner-up in the Electoral College becoming vice president (and the second vote for Burr was discounted and re-assigned to Thomas Jefferson in any event, as it violated Electoral College rules).
Answer in sentence: yes
