Answer:
A Presidential Election is when people run for president. In 1968, Richard Nixon and Hubert Humphrey ran against each other. Nixon won and became president for the first time, before hand he was vice president.
After Nixon served one term (4 years), he ran again against Senator George McGovern. Nixon won again, but shortly after he was getting impeached (kicked out) because of illegal activity during the election. He instead resigned (quit in peace). Vice president Gerald Ford took his place and became president.
