Republicans are trying to hold off Democratic Senate challengers across the country as they look to keep their majority in the chamber.

Democrats lead in three pivotal U.S. Senate races as President Donald Trump falls into a deeper hole in his reelection bid, according to a new CNBC/Change Research poll.

The survey took the pulse of competitive Senate elections in Arizona, Michigan and North Carolina — three of the six 2020 election swing states featured in the poll released Wednesday. The other states — Florida, Pennsylvania and Wisconsin — do not have Senate contests this year.

In Arizona, Democratic former astronaut Mark Kelly leads Republican Sen. Martha McSally by a 53% to 44% margin, according to the CNBC/Change Research poll. The senator, appointed to fill the late John McCain’s seat after she lost a 2018 election in the state to Democratic Sen. Kyrsten Sinema, has consistently trailed Kelly in polls.

Meanwhile, Democratic Sen. Gary Peters of Michigan — one of the few Democratic senators facing a strong Republican challenge this year — holds a 49% to 42% edge over GOP Army veteran John James, the survey found. While Trump narrowly won the state on his way to the White House in 2016, recent polls have showed a challenging environment in Michigan for both the president and James.

In North Carolina, Democratic former state Sen. Cal Cunningham holds a 51% to 41% advantage over Republican Sen. Thom Tillis, according to the CNBC/Change Research poll. A RealClearPolitics average of recent polls shows a much closer race for the Senate seat.
