Martin Van Buren
The founding of the Democratic Party changed politics in America forever, and one of the people credited for its creation is Martin Van Buren. He was one of the founders alongside Andrew Jackson. Buren had many titles to his name and served as the governor of New York, the Secretary of State, the Vice president, and finally, the president of America; the man did it all and did it well.
He campaigned in elections many times and won in 1836 but failed to get reelected in 1840. Van Buren ran for president a final time in 1848 under the Free Soil Party and also famously opposed the expansion of slavery.
