While most state legislatures aren’t up for election until 2018, all 100 members of Virginia’s House of Delegates will go before voters this November. Here at Daily Kos Elections, we’ve been hard at work calculating the results of the 2016 presidential election for each seat, and the numbers are both very revealing—and, potentially, very promising.

Here’s the good news: Hillary Clinton carried the Old Dominion 50-45 last fall, and she also won 51 of the 100 seats in the state House, despite the fact that Republicans drew these very lines to benefit themselves during the last round of redistricting. What’s more, even though Barack Obama won a similar 51-47 victory four years ago, he only carried 47 state House seats, so recent trends are in Democrats’ favor. (To let you drill down further, Stephen Wolf has created an interactive map to show which seats are represented by which party, and who won each seat in the presidential race.)

However—and it’s a big however—despite how seemingly blue their own map is, Republicans currently hold a huge 66 to 34 majority in the chamber (there’s one vacant Democratic seat in a safely blue district). It’ll be very challenging for Democrats to overcome that gap this year, but in this age of Trump, the party simply has to try its hardest to win as many seats as it can, and there are a lot of potential targets for Team Blue.

In fact, no fewer that 17 Republicans sit in seats that backed Clinton last year. The Republican in the bluest seat is James LeMunyon, who represents HD-67, a Northern Virginia district that Clinton carried 60-34; in 2012, Obama won it by a considerably smaller 54-45 margin, which shows how hostile voters there were to Trump—a pattern we’ve seen in other well-educated suburbs.

But other seats moved in the opposite direction. At the far end of this batch of Republican-held seats Clinton won, Hampton Roads Del. Robert Bloxom Jr. sits in the closest district: His HD-100 voted for Clinton 49-47, a drop from Obama's 55-44 win here. But at least Democrats don’t have to worry too much about playing defense: All 34 Democrats sit in Clinton seats, and even the closest—Del. Roz Tyler’s HD-75 in southern Virginia—still went for Clinton by a comfortable 57-41 margin (four years ago, Obama took it 62-37).
