Final answer:
The 'corrupt bargain' significantly impacted John Quincy Adams's presidency by delegitimizing his presidency in the eyes of many, leading to the creation of the Democratic Party, and making his administration less effective due to resistance from Jackson's supporters.
Step-by-step explanation:
The term "corrupt bargain" refers to the alleged deal between John Quincy Adams and Henry Clay in the presidential election of 1824. No one candidate won a majority of electoral votes, thus the decision went to the House of Representatives. Adams, who eventually won the presidency, then appointed Clay Secretary of State, leading opponents to Cry foul with allegations of a 'corrupt bargain'.
This impact on Adams's presidency was significant. First, it delegitimized his presidency in the eyes of many citizens, which strained his relationship with the public. Second, it led Andrew Jackson, another candidate in the same election, and his supporters to break away and form the Democratic Party, which introduced a new era of two-party politics. Third, it subdued the effectiveness of Adams' administration as he faced resistance from Jackson's supporters in Congress.
