The most important point made in the debate between Biden and Trump back in June was this point made by President Joe Biden:

Donald Trump was the worst president in the history of the United States.

Biden provided two good reasons in support of this strong claim:

1. Presidential historians ranked Donald Trump as the worst president in the history of the United States.

Biden: Presidential historians “voted who was the worst president in American history. From best to worst. They said (Trump) was the worst in all of American history.”

True. The 2024 Presidential Greatness Project Expert Survey, released in February, collected responses from 154 presidential historians, which included current and recent members of the American Political Science Association. The survey ranked Biden as the 14th best president in U.S. history, and put Trump last.

The historians were asked to give every president a score, from zero to 100. Abraham Lincoln topped the list with an average score of 95, while Biden scored an average of 62.66. Trump averaged just under 11 points.

2. 90% of Trump’s previous cabinet members are NOT endorsing Trump to be president again.

During the debate, Biden claimed that only 4 out of 44 of Trump’s cabinet members supported his candidacy for the 2024 Presidential race. This is true, based on a report from NBC News:

Donald Trump may have put them in the most powerful and prestigious jobs many will ever hold, but few who worked in his Cabinet are rushing to endorse him in his bid to return to the White House.

NBC News reached out to 44 of the dozens of people who served in Trump’s Cabinet over his term in office. Most declined to comment or ignored the requests. A total of four have said publicly they support his run for re-election. Several have been coy about where they stand, stopping short of endorsing Trump with the GOP primary race underway. Then there are those who outright oppose his bid for the GOP nomination or are adamant that they don’t want him back in power.

Here is a reminder from Robert Reich of the many reasons why Trump was the worst president in the history of the United States:
