THE POST’s endorsements in Northern Virginia’s contested races for the House of Delegates continue today, with our choices appearing in bold type. Previously endorsed races are online at

To determine your legislative district and candidates on your ballot, go to

District 32: When he won a seat in the House in 2009, Republican Thomas A. “Tag” Greason glibly said that Virginia could improve its schools and roads without raising taxes. He turned out to be educable: Mr. Greason, distinguishing myth from reality, voted this year for the transportation bill that will deliver billions of dollars in new taxes to repair and expand the state’s ailing road network. He also successfully pushed to require insurance companies to provide coverage for autistic children. His Democratic challenger, Elizabeth Amy Miller, a longtime pro-choice advocate, is a worthy opponent, but Mr. Greason deserves reelection.

District 33: If it had been up to Republican Dave A. LaRock, Virginia’s transportation system, already decrepit after a quarter-century of dwindling revenues, would continue crumbling — and the state’s commuters would face ever-longer drive times. What’s more, Mr. LaRock, a developer, would kill off the Silver Line to Dulles. His doctrinaire opposition to investing in infrastructure helped him to defeat the Republican incumbent, Joe May, in the GOP primary. Voters in the Loudoun County district would be much better served by Democrat Mary L. Costello Daniel, a moderate member of the Berryville Town Council who would be a problem-solver in Richmond, not an ideological crusader.

District 34: Barbara J. Comstock, a two-term Republican with one of the most ideologically rigid voting records in Richmond, likes to cite her legislation extending tax breaks to data centers in Northern Virginia. But by opposing Virginia’s transportation funding bill, she became part of the problem that has plagued her district’s commuters. Ms. Comstock, who took Grover Norquist’s pledge against any new taxes, cast other doctrinaire votes in favor of mandating transvaginal ultrasounds for women considering abortions and eliminating reasonable limits on gun purchases. A prodigious fundraiser, she has managed to obscure her record by stressing anodyne issues like combating Lyme disease. Voters in her district, which stretches from McLean in Fairfax County to northwest Loudoun County, shouldn’t be fooled. Democrat Kathleen J. Murphy, a former official at the Commerce Department and USAID, would be an improvement.

District 35: Democrat Mark Keam, a two-term incumbent, has made his mark as the driving force behind successful legislation to help veterans and promote sustainable energy. He’s the easy choice in this Fairfax County district over Republican Leiann L. Luse, who has not mounted an active campaign.

District 37: David L. Bulova, the level-headed, hard-working Democratic incumbent, has pushed sensible bills to fight human trafficking and cut burdensome state rules on public schools. His opponent, Republican Patrice M. Winter, a former member of the Fairfax City Council, is a civic-minded moderate who has waged a serious campaign, but she has offered no compelling rationale for replacing Mr. Bulova.

District 38: Democrat L. Kaye Kory, a two-term incumbent, is a conscientious lawmaker who faces only nominal opposition from an independent challenger, James L. Leslie.

District 40: For the decade that Republican Timothy D. Hugo has represented this traffic-clogged district centered in western Fairfax and northern Prince William counties, he has opposed virtually every politically viable means of finding sustainable funding to clear clogged roads for his traffic-weary constituents. He has also stirred up animosity toward undocumented immigrants and, more than any other member of the General Assembly, abused rules that allow lawmakers to charge even routine daily expenses to their campaign accounts. His opponent, Democrat Jerry L. Foltz, a retired pastor who led a day-labor center in Centreville, would be a breath of fresh air.

District 41: Democrat Eileen Filler-Corn, formerly a lobbyist for Virginia on Capitol Hill, is a promising lawmaker finishing her first full term in office. Her Republican opponent, Fredy Burgos, offers tea-party rhetoric but no real promise that he would be effective.

District 42: Republican David B. Albo, a 20-year incumbent, was for years one of the key lawmakers pushing for a sustainable solution to the state’s transportation funding crisis. That effort paid off this year. The Democratic candidate, Ed R. Deitsch, is no match for Mr. Albo.

District 43: Democrat Mark D. Sickles, a 10-year incumbent, has focused on useful legislation to attract and retain biotech firms in Northern Virginia. His opponent, G. Gail Parker, of the Independent Green Party, is a perennial candidate for one office or another.

District 44: Democrat Scott A. Surovell faces only nominal opposition from an independent challenger, Joseph A. Glean. Mr. Surovell successfully pushed for a major study that will provide a blueprint for transportation and development in the Route 1 corridor, which is in sore need of revitalization.

District 45: Although freshman Democrat K. Rob Krupicka won a special election to the House only last year, he has been effective in pushing for funds to train mental-health workers. He faces no serious opposition from Jeffrey J. Engle, an independent.

District 47: Democrat Patrick A. Hope, a health-care attorney, is a four-year incumbent who has pushed to protect nursing home residents’ rights and for sensible gun control. He’s the easy choice over Laura R. Delhomme, a libertarian and relative newcomer to Virginia.

District 49: Democrat Alfonso Lopez, a smart, politically savvy incumbent, made an impact as a freshman by helping to create a state trust fund for affordable housing and protecting funding for centers that help child sex-abuse victims. His opponent, Terrence W. Modglin, a retired Capitol Hill staffer, has run a substantive and civil campaign but makes no real argument for unseating Mr. Lopez.
