Why did John Quincy Adams have miserable presidency?

John Quincy Adams' presidency (1825-1829) was marked by significant political opposition and a lack of popular support, primarily due to his controversial election that was perceived as a "corrupt bargain" with Henry Clay. His attempts to promote ambitious national programs, including infrastructure improvements and scientific advancement, faced resistance from a Congress dominated by his political rivals, particularly the Jacksonian Democrats. Additionally, his strong stance against slavery and advocacy for Native American rights alienated many constituents. This combination of factors contributed to a frustrating and largely ineffective presidency.
