RICHMOND, Va. (AP) — Energized Democratic opposition to President Donald Trump means Virginians will have a lot more choices when they pick members to the state House of Delegates this year.

But many Democratic candidates will be facing a stacked deck as Virginia is one of several states where favorably drawn districts have given Republicans a measurable advantage in past elections, an Associated Press analysis shows.

The AP scrutinized the outcomes of all 435 U.S. House races and about 4,700 state House and Assembly elections last year, using a new statistical method of calculating partisan advantage designed to detect potential political gerrymandering.

The analysis found that Virginia was among those states with Republican-skewed state House districts as well as congressional districts.
