Current Senate: 51 D and 49 R
Final Prediction: 50 D and 50 R
Democrats to pickup TX. Republicans to pickup MT and WV.
Races are categorized as either likely or unlikely to be competitive. I put all open-seat races on the competitive list. This post will be updated continuously until election day.
Rating: Leans Democratic hold
Independent: Krysten Sinema (incumbent)
Overview: (6/20/23) The bad news is Krysten Sinema, now an "independent" still caucusing with the Democrats, may run for reelection. Although she has no chance of winning, she might siphon enough votes from Ruben Gallego to hand this race to the GOP. The good news is that Gallego is a great candidate, Arizona is trending blue, and Arizona Republicans are having a hard time coming up with a strong candidate.
(12/3/23): So far it looks like Sinema is running as an independent, and Republicans will get stuck with batshit-crazy former journalist Kari Lake, who still believes she is the Governor of Arizona even though she it not. Polls suggest Lake and Sinema will split the conservative vote, allowing Ruben Gallego to win with a plurality.
Rating: Likely Democratic hold
Overview: (12/3/23): California has a jungle primary, and it's looking like the runoff could be between two Democrats. That could give a big boost to Democrats in California up and down the ticket.
Rating: Guaranteed Democratic hold
Democrat: Congresswoman Lisa Blunt Rochester (incumbent tom Carper retiring)
Republican: ?
Overview (12/3/23): This race is competitive in name only. Democrat Lisa Blunt Rochester will win.
Florida
Rating: Likely Republican hold
Republican: Rick Scott (incumbent)
Democrat: Former Congresswoman Debbie Mucarsel-Powell
Overview 12/3/23: Scott is the overwhelming favorite at this point. There is the chance, however slim, that Florida will swing back to the left a bit. The Republican hegemony in Florida is increasingly unpopular.
Indiana
Rating: Guaranteed Republican hold
Republican: ? (incumbent Mike Braun retiring and running for Governor)
Democrat: ?
Overview 12/3/23: Mike Braun (R) is retiring to run for Governor, but Democratic chances in Indiana have gone from slim to none.
Overview 12/3/23: This race is competitive in name only. Democrat Angela Alsobrooks will win.
Overview (6/20/23): This one's probably simple. Biden beat Trump by 3% in Michigan in 2020, and the Democrats are likely to field a stronger candidate than the Republicans.
(12/3/23): James Craig is the black former Detroit Chief of Police. The idea that he could cobble together a victory by uniting Michigan Republicans and some of the urban black vote is an intriguing one, but I'll believe it when I see it. Craig tried to run for Governor in 2022, and it went pretty badly. Democrat Elissa Slotkin is running a strong campaign.
Republican: Businessman Tim Sheehy
Overview (6/20/23): Republicans are more likely to win this seat than incumbent Jon Tester, but he's defied expectations in the past. In 2012, Tester won 48.6% to Republican Denny Rehberg's 44.9% with the Libertarian candidate taking 6.6%. This happened while Mitt Romney beat Obama by 14% in Montana. Tester pulled off an impressive 50.3% to 46.8% victory in 2018. But I think his luck might be about to run out. Democrats have preformed abysmally in the past couple of elections in the northern plains.
(12/3/23): It looks like Republicans are going with racist, misogynist homophobe and political novice Tim Sheehy. Tester is polling well against Sheehy, but he will need every possible break to win.
Nevada
Rating: Likely Democratic hold
Democrat: Jacky Rosen (incumbent)
Republican: ?
Overview (6/20/23): Rosen is vulnerable in light-blue Nevada, but so far the Republicans haven't been able to find a top-tier candidate.
(12/3/23) Rosen is benefiting from the fact that big-name Nevada Republicans have declined to join this race. She's likely to face a political novice with little fundraising ability as her opponent.

Rating: Likely Democratic hold
Republican: ?
Overview (12/3/23): Incumbent Bob Menendez is going to jail. Although he hasn't said he's for sure not running for another term, it doesn't matter. The New Jersey Republican party is in bad shape and Democrats have little to fear in this race.
Texas
Rating: Toss up
Republican: Ted Cruz (incumbent)
Democrat: Congressman Colin Allred (likely)
Overview (6/20/23): So Trump only carried Texas by 5 points in 2020. If the GOP ticket proves a total disaster in 2024 (Trump running from prison or something), Texas might actually go blue. That could spell trouble for Ted Cruz who only won by 3 points in 2018.
12/3/23: The $13 million Allred has raised sounds impressive until you realize that Cruz has raised $40 million. Democrats should not kid themselves about this one; it will take a miracle to win.
Utah
Rating: Guaranteed Republican hold
Republican: State House Speaker Brad Wilson? (incumbent Mitt Romney retiring)
Democrat: ?
Overview 12/3/23: This race is competitive in name only. The Republican will win.
West Virginia
Rating: Guaranteed Republican pickup
Democrat: ? (incumbent Joe Manchin retiring)
Republican: Governor Jim Justice (likely)
Overview (12/3/23): This race is competitive in name only. Republican Jim Justice will win.
Republican: ?
Overview (6/20/23): So far no Republican has announced to run against Tammy Baldwin. She's looking like a pretty good bet in Wisconsin, which, after trending red for years has started swinging back a bit towards blue. Janet Protasiewicz's 11 point win in this year's Wisconsin Supreme Court race is a good sign.
Overview (12/3/23): It's still the sound of silence on the Republican side. That's good - the less interested Wisconsin Republicans are in voting in 2024, the more likely Joe Biden wins.
Unlikely to be competitive:
Missouri: Josh Hawley (R) is a contemptible human being; Missouri doesn't care.
North Dakota. Kevin Cramer (R). Does this state even still have a Democratic party?
Pennsylvania: Bob Casey Jr. (D). Could become competitive but I'll believe it when I see it.
Tennessee: Marsha Blackburn (R) is the perfect representative of the ultra-right-wing politics that have gripped Tennessee.
Virginia: Tim Caine (D). Democrats sometimes receive nasty shocks in Virginia, but with Biden likely to carry the state by double-digits this race is unlikely to be competitive.
