Presidential power can shape history—for better or worse. While many U.S. presidents have guided the nation with strength and integrity, others made decisions that left long-lasting negative impacts. So, who was the top 5 worst presidents in American history?
In this post, we’ll take a closer look at the most criticized U.S. presidents, the mistakes that defined their time in office, and why historians consistently rank them among the worst. This is more than opinion—it’s based on measurable failures, public trust erosion, and historical damage.
Top 5 Worst U.S. Presidents of All Time
Here’s a clear summary table based on expert historical evaluations, public opinion polls, and overall legacy:
| Rank | President | Years in Office | Main Failures |
|---|---|---|---|
| 1 | James Buchanan | 1857–1861 | Ignored the rising threat of civil war, failed to act against secession |
| 2 | Andrew Johnson | 1865–1869 | Opposed civil rights, vetoed Reconstruction progress |
| 3 | Herbert Hoover | 1929–1933 | Poor response to the Great Depression, high unemployment |
| 4 | Richard Nixon | 1969–1974 | Watergate scandal, first president to resign |
| 5 | George W. Bush | 2001–2009 | Iraq War failure, slow Hurricane Katrina response |
Buchanan’s inability to prevent Southern states from seceding is often blamed for paving the way to the Civil War. His inaction and pro-Southern sympathies worsened national division at a critical time in U.S. history.
2. Andrew Johnson
Coming right after Abraham Lincoln’s assassination, Johnson had a chance to support a unified nation—but instead he opposed civil rights laws, vetoed key Reconstruction bills, and allowed Southern states to roll back Black progress.
3. Herbert Hoover
The Great Depression hit during Hoover’s presidency—and his failure to act quickly or strongly made it worse. He rejected direct aid and insisted the economy would fix itself, leading to massive unemployment and suffering.
4. Richard Nixon
Nixon achieved major foreign policy wins, but his downfall came with the Watergate scandal. Caught covering up a break-in, he lied to the American people and Congress, eventually resigning before he could be impeached.
5. George W. Bush
Bush’s presidency is deeply controversial. His decision to invade Iraq based on faulty intelligence led to thousands of deaths and a long war. His slow response to Hurricane Katrina also drew heavy criticism.
Why Do These Presidents Rank Among the Worst?
Presidents are judged not only by what they do, but by what they fail to do. The worst presidents:
- Ignored national crises
- Acted against civil rights progress
- Abused power or misled the public
- Made poor foreign policy decisions
- Failed to unite the country in key moments
These leaders were not just unpopular—they damaged public trust, allowed inequality to spread, or failed in moments of national need.
