Why Senate Democrats Are Outperforming Biden in Key States

It was a Pride Weekend in Wisconsin, a natural time for the state’s pathbreaking, openly gay senator to rally her Democratic base, but on Sunday, Tammy Baldwin was far away from the parades and gatherings in Madison and Milwaukee — at a dairy farm in Republican Richland County.

“I’ll show up in deep-red counties. and they’ll be like, ‘I can’t remember the last time we’ve seen a sitting U.S. senator here, especially not a Democrat,’” said Ms. Baldwin, an hour into her unassuming work of handing out plastic silverware at an annual dairy breakfast, and five months before Wisconsin voters will decide whether to give her a third term. “I think that begins to break through.”

Wisconsin is one of seven states that will determine the presidency this November, but it will also help determine which party controls the Senate. President Biden and former President Donald J. Trump are running neck-and-neck in the state, which Mr. Trump narrowly won in 2016 and Mr. Biden took back in 2020.

Ms. Baldwin, by contrast, is running well ahead of the president and her presumed Republican opponent, the wealthy banker Eric Hovde. Polls released early last month by The New York Times, The Philadelphia Inquirer and Siena College found Ms. Baldwin holding a lead of 49 percent to 40 percent over Mr. Hovde. In late May, the nonpartisan Cook Political Report put the spread even wider, 12 percentage points.

That down-ballot Democratic strength is not isolated to Wisconsin. Senate Democratic candidates also hold leads in Arizona, Michigan, Nevada and Pennsylvania. A Marist Poll released Tuesday said Mr. Trump led Mr. Biden in Ohio by seven percentage points, but Senator Sherrod Brown, a Democrat, leads his challenger, Bernie Moreno, by five percentage points, a 12-point swing.
