The US Senate races for 2024 are likely to be tough times for Democrats, who have to defend 23 seats, while Republicans have to defend only 10 seats.
Four Democratic seats–in Maryland, Montana, Ohio, and West Virginia—are greatly endangered, and with only a 51-49 majority in the US Senate, including three Independents (Bernie Sanders of Vermont, Angus King of Maine, and Kyrsten Sinema of Arizona), who ally with the Democrats, but Sinema’s seat also in play if she decides to run again as an Independent after breaking her ties with the Democrats, as it would create a three way race in that state.
Only three Republican seats out of 10 are in some danger, but likely to remain Republican—Florida with Rick Scott, Missouri with Josh Hawley, and Texas with Ted Cruz.
So while it seems highly likely that the House of Representatives will switch from Republican control to Democratic control, with 17 Republican controlled seats being Joe Biden districts won in 2020, it is highly likely that we will still see divided Congressional government with a possible Republican controlled Senate, and continued gridlock and stalemate operating in the legislative branch of government in 2025-2026!
