Kristin Cabral, a McLean lawyer, is the presumptive Democratic nominee for Virginia’s 10th Congressional District in this November’s elections.

According to Charlie Jackson, 10th Congressional District Democratic Chairman, Cabral was the only person to file; that puts her as the prime candidate to take on 16-term incumbent Republican Frank Wolf.

Prior to Cabral’s filing, 10th Congressional Democrats were expected to nominate a candidate via convention in May. With her submission, Jackson said, the convention is unnecessary. The Democratic chairman is expected to certify Cabral’s candidacy with the Virginia State Board of Elections later this month.

Cabral has lived in Northern Virginia for more than 20 years. She’s married with two teenage children.

The 10th District currently includes Loudoun, Clarke and Frederick counties, the cities of Manassas, Manassas Park and Winchester, and large portions of Fairfax and Prince William counties.

In 2010, Wolf defeated Democrat Jeff Barnett by taking 63 percent of the vote. Barnett garnered 35 percent, while Libertarian Bill Redpath took 2 percent.
