The two Republican candidates for the House of Delegates in Tuesday's GOP primary served with distinction in Vietnam and gave up higher paying work to serve in public office. But that's about all incumbent Richard H. "Dick" Black and challenger Dave McWatters have in common.

The two candidates seeking the GOP nomination for the 32nd House District, which includes part of Loudoun County and a sliver of Fairfax County, represent opposite wings of the Republican Party.

Black, who took office after a special election last year, is among the most conservative members of the General Assembly, advocating antiabortion license plates and additional restrictions on abortion and Internet pornography. McWatters, a Loudoun County supervisor from the Broad Run district, is more moderate and has pushed regularly for more funding for schools, even if doing so required increasing taxes.

They portray each other as extreme, and some political analysts say the race could be a bellwether of the future of Republican politics in Northern Virginia.

"He's the poster child for the extreme right wing," McWatters said.

"There's no doubt that McWatters would be one of perhaps three of the most liberal Republican members of the House of Delegates were he elected," Black said.

The winner of the GOP primary will face Democrat Kelly Burk in November. Burk, president of the Loudoun Education Association, faces no opposition in the primary.

McWatters, a Realtor, has served 3 1/2 years on the Board of Supervisors. Black, a lawyer, won a special election in February 1998 after then-Del. William C. Mims (R-Loudoun) won election to the state Senate.

McWatters is running on a platform that calls for more tax dollars to be returned to localities to pay for schools. He wants more money for teacher salaries and transportation projects.

He also has said the General Assembly should do more to help suburbs battle sprawl. As a supervisor, he endorsed a measure that would have allowed localities to cut off development in areas where there were not enough roads or schools. That measure, along with several other growth-control bills, failed in the General Assembly.

Last week, Black began campaigning on a slow-growth theme, branding his opponent "Sprawl McWatters" in advertising. Black criticized McWatters for failing to support fees for developers on every house they build; McWatters said he opposes such measures because they add to the cost of housing and price middle-class people, such as sheriff's deputies and teachers, out of the market. Black also criticized McWatters for supporting a county policy that allows some residential developers to build to a higher density if they include low-cost housing.

McWatters has the backing of a Loudoun group called Voters to Stop Sprawl, which said McWatters has a better record on the growth issue.

Black said he wants to continue to focus on "family value" issues in the General Assembly.

Black has been a controversial figure in the legislature because of his efforts against abortion and pornography and his proposal to make it legal to carry concealed weapons in restaurants and bars that serve alcohol. Black also said he wants to continue working on transportation issues and to look for regional solutions to gridlock.

When Black served on the Loudoun Library Board before taking office, he helped craft a policy requiring the use of filtering software on computers with Internet access as a way to prevent patrons from viewing pornography.

The policy was ruled unconstitutional by a U.S. District Court judge, and despite Black's call for an appeal, the current Library Board declined and has altered the policy. After his election, Black proposed unsuccessful legislation that would have required filters on public school computers.

"I have done everything that I could conceivably do to keep vice and corruption out of the county -- particularly through the battle with the Internet," Black said. "I've got an opponent who mocks opponents of pornography, who denigrates their efforts. He clearly is on the other side."

McWatters said that he wants to keep pornography out of libraries but that requiring adults to use the filtering software could violate free-speech rights. He said that Black has become "obsessed" with the issue and that he should spend his time addressing concerns of greater significance to constituents. He also criticized Black for taking a television reporter into a Loudoun library and pulling up World Wide Web pages that Black said contained "gruesome" images of rape victims.

"We never ever in the history of this county ever had people go to the library and pull [up] pornography on the screen," McWatters said. "Now we've got one."

Black said he did it to show what kinds of Web pages children could view.

If elected, what will be your two top legislative priorities in the General Assembly and why? How would you gain support for those measures to ensure their passage?

As Gov. James S. Gilmore III has said, I have worked "tirelessly to mitigate the effects of rapid growth in Northern Virginia." Transportation and education are my top priorities. I have worked successfully with Gov. Gilmore to secure $13 million to widen Route 7 toward Tysons Corner and fund $10.1 million to rebuild Route 15.

I voted to return 100 percent of lottery proceeds to schools. I introduced the Teacher Tax Credit bill. My bill to make public schools free to children who are in adoption proceedings was passed into law this year. I co-sponsored a bill with Sen. William C. Mims to improve school construction funding. Additionally, I voted to support the governor's pledge to cut the car and food tax and allow taxpayers to keep more of their money. Together we enacted the largest tax cuts in Virginia's history.

These accomplishments are possible because I have built strong relationships with many of the key people in Richmond. I have been endorsed by Gov. Gilmore, Attorney General Mark L. Earley and Sen. Mims because we have worked successfully together.

If elected, what will be your two top legislative priorities in the General Assembly and why? How would you gain support for those measures to ensure their passage?

I would continue to bring more education dollars back to localities. Virginia's Composite Index formulation benefits other parts of the state. Continue to support Del. Joe T. May's legislation to return more dollars to our jurisdiction. Also, by continuing to control runaway development by supporting such incentives as the Adequate Public Facilities Ordinance and other issues. Continue trend to slow development (voted to reduce density in county by 80,000 and voted to reject thousands of unwanted development units). These can be accomplished by working with delegates and senators with whom I have worked for years on many issues. Build on the rapport I already have with many legislators to form a consensus to bring back the much needed dollars for better teachers' salaries and school construction. Virginia is the only state in the country that doesn't participate in school construction. I would work to bring all lottery money back to the district collected from and introduce legislation to require a percentage of carry-over funds to be applied to education.

I would continue to improve our county's quality of life for our citizens. Specifically, we must continue to fight legislation that allows students to take guns to school; continue to resist legislation introduced by opponent to allow concealed weapons to be carried into restaurants; support the Library Board's current policy to filter access of minors to the Internet; obtain more funding for road improvements, especially Route 15 and Route 7. The committee I serve on (TCC Executive Committee) originated the Northern Virginia Transportation Bonds, which during the past two years resulted in funds for improving Route 15 and for the coming cloverleaf at Route 28 and Church Road. I have an excellent relationship with all Northern Virginia legislators which was very helpful when trying to get our share and more from the state bonds.
