J.J. (Jack) Caussin (R), 48, of 6011 Roxbury Ave., Springfield, is a faculty member at the Holton-Arms School. He is a former Fairfax County School Board member, and was chairman for the Republican Party's Springfield District for three years. He has also served on the Gunston Hall Board of Visitors. Answer: Transportation, education, Lorton, housing and crime are issues confronting Fairfax County citizens. They have been the subject of much discussion, all of which sounds similar. The difference is who has the breadth of community experience and who has the knowledge of the people represented to best deal with these and other issues. The difference is Jack Caussin. The difference is:

* A plan to minimize the discretionary practice of highway funding in Northern Virginia. The ability to take a hard look at a budget. My school board experience has proven that I am stringent with the taxpayer's dollar.

* The ability to look at education from both sides. I have been on the governing body for schools and I am a classroom teacher.

* A strong belief in uniform and mandatory sentencing in drug- and alcohol-related cases.

* Experience as a proven commmunity leader possessing the ability to work with all kinds of people. Robert K. (Bob) Cunningham (R), 61, of 7829 Greeley Blvd., Springfield, is chairman of the 8th Congressional District Republican Committee. He was an Army colonel and later a project manager for the Westinghouse Electric Corp. before retiring in 1977. He has a master's degree in foreign affairs. Answer: Bob Cunningham has unequaled credentials to serve as delegate in the General Assembly, the position that he seeks. His 26-year career of leadership and management with the federal government, combined with nine years' experience in the private sector, make him a uniquely qualified candidate. Cunningham's long-time party and campaign posts have resulted in close and harmonious working associations with elected officials and statewide party leaders. These associations are enhanced because of his membership on the state executive committee of the Republican Party of Virginia and on the Republican State Central Committee. With this background, Cunningham would be entering the General Assembly with much more practical experience than the average freshman. Because he is fully retired, Bob Cunningham can devote his full time and energies to the representation of his constituency. He feels this is extremely important, since he sees the position of delegate as serious, year-round, full-time representation. Bruce L. Green (R), 35, of 7195 Duck Ct., Springfield, is vice president of business development for Mount Vernon Realty Inc. He is chairman of the Springfield District Republican Party and serves on the board of directors of the Fairfax chapter of the American Red Cross. Answer: I am more people-oriented than my opponents. This is reflected in my professional, civic and political activities. I have been in the real estate business for 13 years and have had the opportunity to work on a one-to-one basis with many families, helping them find a home, often their first in this area. To fully represent their interests, I've had to develop a good understanding of the quality of the education system at the local level, not as an educator but as a consumer. I have also had to deal with a major concern of most people: access to work and shopping. Thus I am more familiar with local transportation and traffic issues. I am the only candidate who has established a citizens' advisory committee to provide the opportunity for my constituents to have an input in the development of my platform before I go to Richmond. William P. Whalen Jr. (R), 39, of 7005 Ridgeway Dr., Springfield, owns Reality Realty, a consumer residential real estate counseling firm. He has been active in Republican Party politics on the local level, doing door-to-door canvassing and monitoring polling places. Answer: I feel strongly that the most important reason I should be elected instead of my opponents is that, like many politicians, they promise the voters everthing from solving crime, reducing taxes, eliminating transportation problems, etc., without getting to the core of leadership. Namely, helping fellow citizens with their "personal problems" as they relate to government. In short, from some 20 years of personal experience, I have leaned that when no one else seemed to care and all remedies were tried, there were a few leaders that did care. These experiences have formed my basic desire to serve the people. If history tells us anything, it is that no one person can solve our public problems. It requires a major group effort. I will work aggressively to try and solve some of our problems with the help of other political leaders, but I will promise but one thing: To be your hand-picked representative and link with your state government, and to represent you and your neighbors. If I can't do it, you can be certain I am going to try. That I can do. I need your help.
