RICHMOND, Va. (AP) — Virginians cast ballots Tuesday to decide which party should control the statehouse in a widely watched contest that will test how voters feel about President Donald Trump and his possible impeachment.

The Old Dominion’s legislative elections are serving as the marquee warmup for the 2020 election cycle as well as a referendum on the state’s gun laws and abortion rights. Outside groups and political parties are test-driving expensive campaigns to win over and motivate voters in a state that was until recently considered a presidential battleground.

Of the four states holding legislative elections this year, Virginia is the only one with control of the statehouse up for grabs. Republicans have a slim majority in both the state House and Senate, but Virginia has been trending blue for years thanks to growth in more diverse, liberal suburbs and cities, and population declines in more rural, conservative areas.

Democrats are hoping voters send a message that the anti-Trump energy that has powered blue waves in the last two elections is still robust.
