Northern Virginia will have three contested primaries for House of Delegates on Aug. 23, including two for new districts created due to once-a-decade redistricting, according to the State Board of Elections, which certified candidates for the ballot.

In the new district 87, which includes Loudoun and Prince William counties, two Republicans are battling for the GOP-leaning seat.

Jo Ann Chase , a broker who serves on the Republican Party’s State Central Committee and the Republican National Hispanic Assembly of Virginia, faces David Ramadan , an international consultant who sits on the George Mason University Board of Visitors.

Del. Bob Marshall, one of the most conservative members of the House, and former delegate Dick Black, who is running for state Senate, have endorsed Chase. Dels. Jackson Miller, Tag Greason and Jim LeMunyon have endorsed Ramadan.

In the other new district, which encompasses Clarke, Frederick and parts of Loudoun County, there’s a three-way race for the GOP primary.

Lawyers Randy Minchew and John Whitbeck face Cara Townsend, a small-business owner.

Del. Adam Ebbin’s decision to run for state Senate has left his Democratic-leaning seat in Alexandria up for grabs.

Alfonso Lopez, who worked for the U.S. Small Business Administration and was Gov. Tim Kaine’s director of the Virginia Liaison Office, faces Stephanie Clifford, director of special events at the Podesta Group.
