Richard Nixon won the 1972 U.S. presidential election by a large margin. He defeated the Democratic Party nominee, George McGovern, by winning 60.7% of the popular vote and 520 electoral votes out of 537. This was one of the largest landslides in U.S. presidential election history.
It wasn't imminent at all.
If Nixon wanted to end the republic as we know it, he nearly could have. He had a insane mandate by the people.
