(NEXSTAR) - The 2024 presidential election is fast approaching, and in some states, the voter registration deadline is as soon as this week. Voters in key battlegrounds, including Florida, Arizona, and Georgia, have just days to register, and missing these deadlines could mean losing the opportunity to cast a ballot in what is shaping up to be a pivotal election. In states like Alaska and Rhode Island, voter registration must be completed by Sunday, Oct. 6. Similarly, South Carolina has an Oct. 6 deadline for online registration, while the in-person registration deadline is earlier, on Oct. 4.
