The 1872 election saw President Grant returning for a 2nd term. He ran unopposed from his own party.
Funny enough, Vice President Schuyler Colfax had almost enough delegates to stay on the presidential ticket.
Instead Senator Henry Wilson became his running mate.
Some Republicans were dissatisfied with Grant, and spilt off into the Liberal-Republican party. Horace Greeley became the nominee, oddly enough the Democrats made them their nominee as well in an effort to defeat Grant. Ironically Greeley hated the Democratic party, and never joined them officially.
The campaign was mostly about the issue of how to handle the end of Reconstruction. However the issue of women's rights came in to play with the idea of women's suffrage. Victoria Woodhull became the first woman to be nominated for president, and many women attempted to vote. Susan B. Anthony was one of the many who were fined and arrested for attempting to vote.
Probably the strangest thing to come out of the election was the death of Greeley. His wife died, and he went crazy. He died before the electoral votes were counted. Becoming the only major nominee to die before the end of the election.
That being sad it was an easy victory for Grant with him gaining 286 electoral votes. Most of Greeley's votes were either disqualified or given to minor candidates. You got to imagine how crazy it would have been if he'd won the election?
