EXCLUSIVE: Americans' confidence in the U.S. presidency has hit its lowest point ever under President Joe Biden's administration, the annual Reagan National Defense Survey has found.

According to the survey, just 36% of American adults said they had either a "great deal" or "some" confidence in the presidency, while 17% said they had "a little," and 47% said "not much at all."

Those numbers continue a downward trend since the survey was first taken under former President Donald Trump's administration in Nov. 2018, when 44% said they had a "great deal" or "some" confidence in the presidency. The number of those having not much confidence at all has held steady since then.

The survey also found that just 38% held a favorable view of Biden and 59% an unfavorable view. Trump fared significantly better with a 47% favorable rating and 50% unfavorable rating.

Biden's favorability has fallen sharply since Feb. 2021, just after his inauguration in January that year, when it stood at 53%.

When asked about the 2024 presidential election, 63% of likely Republican voters said they wanted to see Trump as the party's nominee, followed by Florida Gov. Ron DeSantis at 10%, former U.N. Ambassador Nikki Haley at 8%, entrepreneur Vivek Ramaswamy at 4% and former New Jersey Gov. Chris Christie at 1%. All other candidates received less than 1%.
