U.S. President Joe Biden’s public approval rating fell to a new low of 40% this week, a clear warning sign for his Democratic Party as it seeks to retain control of Congress in the Nov. 8 election, according to a Reuters/Ipsos opinion poll.

The national poll, conducted on March 21 and 22, found that 54% of Americans disapprove of his job performance as the country struggles with high inflation and Russia’s invasion of Ukraine has pushed geopolitical concerns to the fore.

Biden’s approval rating, down three percentage points from the prior week, mirrors that which his Republican predecessor, Donald Trump, received at this point in his presidency, as both stood at 40% in mid-March in their second year in office.

Trump’s approval rating sank as low as 33% in December 2017.
