20 states vying to be first to vet 2024 Democratic presidential hopefuls

Twenty state Democratic parties are moving forward with efforts to be the first to vote in the 2024 presidential Democratic primaries — a potential change that will attract more attention if President Biden decides not to run for reelection. 

All four of the states that have kicked off the nominating process since 2008, Iowa, New Hampshire, Nevada and South Carolina, confirmed to CBS News that they are submitting applications to remain in the early window.
