Will Democrats or Republicans have control of the Senate Come January? As of this Tuesday, with a little more than three weeks to go until the midterm elections, it’s not so clear.
There are around five states where there are “toss-up” elections, according to analysis from three different sources: Sabato’s Crystal Ball at the University of Virginia’s Center for Politics, 270 to Win and The Cook Political Report with Amy Walter. The main states in question are Iowa, Kansas, Maine, Ohio and Texas – all currently held by Republicans.
Meanwhile, Ballotpedia identified 12 battleground races: Alaska, Florida, Iowa, Maine, Montana, Nebraska, North Carolina, Ohio and Texas are currently held by Republicans, while Georgia, Michigan and New Hampshire are held by Democrats.
If Democrats manage to win in some of the main five battleground races they would upend decades of GOP control. For example, the battles between Democrat Adam Hamilton and Republican Sen. Roger Marshall in Kansas and between Republican Texas Attorney General Ken Paxton and Democrat James Talarico in the Lone Star State.
According to Sabato’s map, two Senate seats held by the GOP in other states are leaning towards wins for Democrats: Alaska and North Carolina. It didn’t show any potential “flip” seats for Republicans, and it showed that red state Nebraska was “leaning” GOP rather than being in the “likely” or “safe” categories.
While 270 to Win had Kansas labelled as leaning right rather than as a toss-up, it was predicting as of Tuesday that the Democrats would potentially take the Senate. It also cited Polymarket betting data that gave the Democrats a whopping 63% odds of winning the chamber. Kalshi, another betting site, had odds even higher for the Dems on Tuesday at 65%.

However, its combined list of solid, likely or leaning Republican has more states (15) than those solid, likely or leaning Democrat (13).
There are 31 Republican-held Senate seats that are not up for re-election and 34 Democrat-held Senate seats that are not up for re-election. Democrats can take control of the Senate if they win a net of four seats, 270 to Win explained.
