Do political leaders in the US usually do what they are elected to do?

Political leaders in the U.S. often face a complex landscape of competing interests, public opinion, and institutional constraints, which can affect their ability to fulfill campaign promises. While some leaders succeed in implementing their agendas, others may struggle due to partisan gridlock or shifts in priorities once in office. Additionally, the influence of lobbyists and special interest groups can also divert leaders from their original goals. Ultimately, the extent to which they do what they are elected to do varies widely among individuals and circumstances.
