A new NBC News poll shows that while former President Trump still leads a hypothetical GOP primary field, 60% of Americans believe that he shouldn't campaign for the White House in 2024 -- including approximately one-third of Republicans. At the same time, 70% of Americans believe that President Biden shouldn't seek a second term, though 41% of registered voters overall said they would probably or definitely vote for him in the general election if he runs again. Furthermore, 51% of Democrats don't want Biden to run again, citing his age as a major reason.

The poll comes as President Biden is preparing for an expected campaign launch, which could come as early as this week. If he does run, he would have a significant advantage in campaign funds, as he is not likely to face a serious challenger in the Democratic primaries. By comparison, the Republican Party is expected to have a fiercely competitive primary, with former President Trump as the current front-runner. Trump lost the 2020 election by over 7 million votes and most of the candidates he endorsed in the 2022 midterm elections were defeated. Trump also faces several lawsuits and possible indictments, while Biden's campaign would have several major things in its favor, including potentially a massive funding advantage.
