I don’t believe this question truly applies to any of the candidates, but I would have to go with Andrew Jackson. Jackson won the popular vote and had the most total votes, but John Adams still won in electoral college. Therefore Jackson would be your answer because he received the most votes but failed to gain the majority of the electoral college. Have a nice day.

They would work hard and do their best to improve the colony and those not supporting the growth of the colony would be punished.
