Just a month ago, Democrats saw a path to a Senate majority but now look as if they could lose more seats and have a smaller minority next year.
Republicans have seen a bump in the polls in several key races since Labor Day. They believe momentum has flipped to their party since the fight over Supreme Court Justice Brett Kavanaugh polarized the electorate, hurting Democrats running for reelection in states where President Trump is popular.
Two states where Democrats had hopes of pulling major upsets — Texas and Tennessee — have moved in favor of Republicans. Races in Nevada and Arizona, two other states where Democrats had hoped to make gains, remain tight, but Republicans feel more confident about their candidates.
Meanwhile, the tide has moved against Democratic candidates in a couple of states that Trump won by double digits in 2016:
- In North Dakota, Democratic Sen. Heidi Heitkamp has fallen behind by double digits.
- In Montana, Sen. Jon Tester (D), who seemed poised for victory a month ago, has seen his race tighten amid attacks by the president.
