President Joe Biden will not appear on the New Hampshire primary ballot in 2024, marking the first time a sitting president has not done so. This is due to the Delegate Selection Rules for the 2024 Democratic National Convention, which were set in motion earlier this year and are intended to ensure a level playing field for all candidates. Biden's campaign manager wrote a letter to New Hampshire Democrats explaining the decision, and it will be interesting to see how the Democratic Party and its voters respond.
