Will a new five-year farm bill become law by December 31, 2026?

We now estimate a 16 percent chance that a new five-year farm bill becomes law by December 31, 2026, as of October 12, down a point. The Senate bill has not reached the floor, no SNAP cost-shift compromise has been announced, and an expected Democratic House win lowers lame duck urgency, so another extension remains likeliest.

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

As of October 15, 2026, we give Democrat James Talarico a 54 percent chance of beating Republican Ken Paxton, down from 59. Four polls released this week show the race tightening, from a tie to a four-point Talarico lead, and the UT/Texas Politics Project poll finds 92 percent of Republican likely voters now back Paxton.

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 15, 2026, we put the chance that Democrats win the House at 92 percent, up from 91. Republican groups have begun abandoning endangered incumbents, and senior Republicans told Politico the House had all but slipped away. Much of that retreat reflects polling we had already priced, so the move is small; a polling miss is the main risk.

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

As of October 15, 2026, we give Republicans a 34 percent chance of keeping the Senate, up from 33. Texas tightened, with our Talarico forecast down to 54 percent, and Iowa is a true Toss Up rather than a Democratic lean, while Roy Cooper leads by 14 in North Carolina and Troy Jackson still leads narrowly in Maine.

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

As of October 15, 2026, Chuck Schumer is the most likely Senate Majority Leader in January 2027, at 48 percent, up from 46, ahead of John Thune at 32. Our Senate forecast gives Democrats a 66 percent chance of control, and Axios reports Schumer is more than favored to win the caucus secret ballot.

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

As of October 15, 2026, House Democratic Leader Hakeem Jeffries has an 87 percent chance of being elected Speaker in January 2027, up from 86. Our House forecast now gives Democrats 92 percent after Republican groups began abandoning endangered seats, and a new majority almost always elects its leader; Mike Johnson needs a Republican hold.
