Final answer:
John Quincy Adams was largely an unpopular president for various reasons, but the main factors were accusations of stealing the 1824 election and being unwilling to court public approval.
Step-by-step explanation:
John Quincy Adams was largely an unpopular president for all of the following reasons except that he replaced existing officeholders with his political supporters, supported federal construction of roads and a national university, and sought to curb land speculation in the West. However, Adams was seen as having stolen the 1824 election and was unwilling to court or campaign for public approval. His lack of popular support and failure to connect with voters ultimately contributed to his unpopularity as president.
