Democrats have a 4-point advantage over their Republican counterparts in dozens of battleground House districts, according to a new poll released Monday.

The Washington Post-Schar School poll shows likely voters in 69 battleground races favor the Democratic nominee over the Republican candidate by 50 percent to 46 percent. That’s a major shift from 2016 when the same districts favored Republican nominees by 15 percentage points.

Only six of the 69 battleground seats are held by Democrats, who need to pick up 23 seats in the November midterm elections to gain control of the House.

President Trump won 48 of the districts in the 2016 presidential election. Of those districts, likely voters are now split 48 percent for the Democratic nominee and 47 percent for the Republican. In the 21 districts Hillary Clinton carried, Democrats have a 10-point advantage.

Women appear to be bolstering Democratic support in these districts. Women supported the Democratic candidates by 54 percent to 40 percent, while men favored Republicans by 51 percent to 46 percent.

The poll, conducted Sept. 19-Oct. 5, surveyed 2,672 likely voters. It has a margin of error of plus or minus 2 percentage points.
