Will Democrat James Talarico defeat Ken Paxton in the 2026 Texas U.S. Senate race?

As of October 12, 2026, we give Democrat James Talarico a 59 percent chance of beating Republican Ken Paxton, up from 52. All three polls fielded since late September, including the New York Times and Siena, show Talarico ahead by two to six points, but Texas has not elected a Democratic senator since 1988.

Will the U.S. government shut down in December 2026, when the current stopgap expires?

We now put the chance of a federal shutdown starting between December 12 and December 31, 2026 at 27 percent, up from 24, as of our October 12 cutoff. Traders have priced more risk and our window is wider than theirs, but another cheap short stopgap into 2027 remains the likeliest exit when Congress returns.

Will Democrats win control of the U.S. House in the 2026 midterm elections?

As of October 12, 2026, we put the chance that Democrats win the House at 91 percent, up from 88. The Cook Political Report moved 18 House races toward Democrats in its October update, as Axios reported on October 9, tripping our signpost and pointing to a gain well past the three seats needed. Redrawn maps remain the main risk.

Will Republicans keep control of the U.S. Senate in the 2026 midterm elections?

As of October 12, 2026, we give Republicans a 33 percent chance of keeping the Senate, down from 42. New York Times/Siena polls released October 3 showed Democrats ahead in Alaska, Texas and Ohio, later October polls kept Talarico and Brown ahead by four or more, and Maine polls mostly favor Troy Jackson.

Who will be Senate Majority Leader when the 120th Congress convenes in January 2027?

As of October 12, 2026, Chuck Schumer is the most likely Senate Majority Leader in January 2027, at 46 percent, ahead of John Thune at 31. Our Senate forecast now gives Democrats a 67 percent chance of control after October polls showed them ahead in Alaska, Texas and Ohio, though Schumer still faces opposition from several Democratic nominees.

Who will be Speaker of the House when the 120th Congress convenes in January 2027?

As of October 12, 2026, House Democratic Leader Hakeem Jeffries has an 86 percent chance of being elected Speaker in January 2027, up from 84. Our House forecast now gives Democrats 91 percent after Cook moved 18 races their way, and a new majority almost always elects its leader; Mike Johnson needs a Republican hold.
