The first states with polls to close are mostly in the Eastern Time Zone. In the early states, we have two governor’s races (Georgia and Florida), four Senate races (Florida, Georgia, North Carolina, and Ohio), and seven House seats (1 in North Carolina, 3 in Ohio, and 3 in Virginia) that could be close. There are also several seats that are likely to flip solely because of the new maps (4 flipping red in Florida, 1 flipping red in Georgia, and 2 flipping blue in North Carolina).
But the big closing time is 7 p.m. Central ST. The remaining polls will close in Florida, and most of the polls will close in Kansas, Michigan, South Dakota, and Texas. And all of the polls will close in Alabama (except for a very small portion that closed an hour earlier), Connecticut, Delaware, D.C., Illinois, Maine, Maryland, Massachusetts, Mississippi, Missouri, New Hampshire, New Jersey, Oklahoma, Pennsylvania, Rhode Island, and Tennessee. In short, when added to the states that close before 7 p.m., the polls will be closed in roughly half of the country by 7:01 p.m. (Of course, polls closed merely means that individuals need to be in line to vote at 7 p.m. Because there are typically people in line to vote, voting might actually continue in some urban precincts for a very long time after 7 p.m. which will delay counting in those areas.)
Starting with Alabama, there are no races that are likely to be close at the state or federal level. If the Supreme Court follows the Voting Rights Act, Democrats will probably pick up an additional seat in 2024, but the current maps which a district court correctly held violated the Voting Rights Act is in place for the 2022 election, and the 6-1 Republican advantage will remain in place for the next Congress. There are a lot of propositions on the ballot in Alabama, the most significant of which requires changes to election law to be adopted at least six months prior to a general election.
