"Public Concerns Mount as Trump Takes Lead Over Biden in 2024 Race"

A new national NBC News poll reveals that a significant majority of voters have concerns about both President Joe Biden and former President Donald Trump ahead of the 2024 presidential race. Three-quarters of voters express concerns about Biden's age and mental fitness, while nearly two-thirds have concerns about the multiple trials Trump faces. The poll also shows Trump expanding his lead in the Republican presidential nominating contest and a hypothetical rematch between Biden and Trump resulting in a deadlock. Biden faces challenges beyond his age, including high disapproval ratings, dissatisfaction with his handling of the economy, and lagging interest in the election among key parts of the Democratic base. Meanwhile, Trump's lead in the GOP race has grown, but he still faces overall unpopularity with the general electorate.
