During the election of 1824, 4 people elected Henry Clay, Andrew Jackson, John Quincy Adams, and William Haris Crawford.
Henry Clay got kicked out, but after that John Adams started talking to Henry. After a little while, Henry clay made John Adams president even though Andrew had the public opinion.
This caused people to rise in suspicion and start to think that Henry and John had a corrupt bargain and also Andrew Jackson wanted to have revenge and would elect next time.
During the Election of 1828 there was a lot of mudslingers between Jackson and John. But in the end, Andrew Jackson won the election and this was the start of a new good/bad presidency coming to office.
When Jackson went into office he presented himself as a common men which lead to more people liking him and supporting him.
During Jackson presidency, he created the Spoils system which allowed him to get his friends and supporters jobs inside of the office. This lead to people thinking this was unfair and may be unconstitutional.
