Republican Jackson R. Champion, who lost his bid for nomination as mayor in the Sept. 12 D.C. GOP primary election to Arthur A. Fletcher, possibly could appear on ballot in the Nov. 7 general election as Republican candidate for City Council chairman at large member or D.C. delegate.

Champion, who received write-in votes for all three offices, did not get the highest number of votes for any of the posts. But he is eligible to conduct a candidacy if the highest vote-getter in his party declines to run.

Champion received 18 write-in votes for delegate while Fletcher got 40 and D.C. Delegate Walter E. Fauntroy, the Democratic incumbent, got 200 on Republican ballots.

Because Fletcher is a candidate for mayor and Fauntroy is a Democrat, Champion, with the next highest number of write-in votes, could oppose Fauntroy in November.

Champion got 19 write-in votes for council chairman, unofficially second to fellow Republican Jerry Moore, and one more than Fletcher.

It is not clear how many write-in votes Champion won for the at-large City Council seat. But with his party's nomination, he could run for that officer, according to Paul Hays, chairman of the D.C. Republican Committee.

"I don't know what the legal situation is," said Hays. "But it is very probable that the committee will select a candidate for each office . . ." He said the committee would meet soon to interview candidates and make selections.

Fletcher met for about an hour yesterday with 30 members of the Committee of 100 Ministers, a group of ministers who favored Mayor Walter Washington in the Democratic primary. Some have said they would consider endorsing Fletcher's campaign for mayor.
