Though most eyes on Tuesday will be on the New Hampshire Republican primary, Democrats are holding their breath as President Joe Biden‘s campaign viability is put to the test for the first time. He can’t afford to lose this primary — but he also can’t win.

Because the Democratic National Committee replaced the Granite State’s first-in-the-nation status with South Carolina, it will not award delegates to anyone who participates in the unsanctioned primary on Tuesday.
