A new poll from The New York Times and Siena University shows late-deciding voters breaking toward Republican candidates by a nine-point margin in seven competitive Senate races.

The survey, released Sunday night and conducted from October 23 through November 1 among 5,708 likely voters, highlights momentum for Republicans in the closing days before Tuesday's midterm elections. "There are still some undecided voters, and voters who decided only in the last month favored Republicans by a nine-point margin," the Times reported.

Democrats maintain overall leads in most contests. The poll shows Abdul El-Sayed ahead of Mike Rogers by 11 points in Michigan, James Talarico leading Ken Paxton by seven points in Texas, Troy Jackson ahead of Sen. Susan Collins by six points in Maine, former Sen. Sherrod Brown up five points on Sen. Jon Husted in Ohio, and Adam Hamilton ahead of Sen. Roger Marshall by five points in Kansas. Mary Peltola leads Sen. Dan Sullivan by two points in Alaska, while the Iowa race remains essentially tied.

The late-decider trend offers Republicans a potential advantage in tight races, even as Democrats hold edges on issues like the cost of living. Several contests fall within the poll's margin of error, leaving open the possibility of shifts on Election Day. Siena University noted that Democratic control of the Senate remains possible but that a Republican majority cannot be ruled out.

The findings come amid broader polling that has shown volatility in battleground states. Republicans currently hold 53 Senate seats, and Democrats would need to flip four to gain the majority, with Vice President JD Vance available to break ties.

Analysts from both parties have pointed to the final stretch as decisive, with late movement among undecided voters often proving influential in past cycles.
