Five senators, including Paul S. Sarbanes (D-Md.), and 63 representatives, including four Maryland Democrats, had a "perfect" voting record on civil rights in the 1981-82 sessions of Congress, according to the Leadership Conference on Civil Rights.

The leadership conference is a coalition of 160 groups representing blacks, Hispanics, labor, religious organizations, women and the handicapped.

The conference said 52 of the 100 senators and about half the 433 House members scored 50 percent or better in 15 Senate and 11 House votes chosen by the conference to measure civil rights support. The votes came on issues such as voting rights, immigration and desegregation.

Senators achieving 100 percent ratings were Sarbanes, George J. Mitchell (D-Maine), Paul E. Tsongas (D-Mass.), Howard M. Metzenbaum (D-Ohio) and John H. Chafee (R-R.I.). All but Tsongas are up for reelection this year.

The conference said seven senators, including Harry F. Byrd Jr. (Ind-Va.), scored zero, not supporting the pro-civil rights position on any of the 15 votes. Besides Byrd, these included Jeremiah Denton (R-Ala.), James A. McClure (R-Idaho), Steve Symms (R-Idaho), J. James Exon (D-Neb.), John P. East (R-N.C.) and Jesse Helms (R-N.C.).

Maryland's Charles McC. Mathias Jr. (R) rated 87 percent (he missed two votes but was "perfect" on the others), and Virginia's John W. Warner (R) rated 20 percent.

In the House, 63 members, all Democrats, achieved "perfect" pro-civil rights records, according to the conference. They included Maryland Democrats Barbara A. Mikulski, Steny Hoyer, Parren J. Mitchell and Michael D. Barnes.

House members rated zero included seven from Virginia, the most of any delegation. They were Reps. Stanford E. Parris (R), G. William Whitehurst (R), Thomas J. Bliley Jr. (R), Robert W. Daniel Jr. (R), W.C. (Dan) Daniel (D), M. Caldwell Butler (R) and J. Kenneth Robinson (R).

Of the remaining three Virginians, Rep. Paul S. Trible Jr. (R), who is running for the Senate, rated 9 percent, Frank R. Wolf (R) rated 18 percent and William C. Wampler (R) rated 9 percent.

In the Maryland delegation, Rep. Roy Dyson (D) rated 46 percent, Clarence D. Long (D) 82 percent, Marjorie S. Holt (R) 36 percent, and Beverly B. Byron (D) 46 percent.
