RICHMOND, FEB. 17 -- The movement to draft retiring U.S. Sen. Paul S. Trible Jr. (R-Va.) for governor, which already has stirred up a hornet's nest within the state Republican Party, picked up momentum today with the announcement of a formal, 118-member committee of supporters.

The list named 22 of 45 Republicans in the Virginia General Assembly, including Dels. Robert F. Cunningham of Springfield, James H. Dillard II of Fairfax, Harry J. Parrish of Manassas and J.A. (Jack) Rollison III of Woodbridge. Also included were half of the local GOP city and county chairmen in the state.

Sen. Wiley F. Mitchell Jr. (R-Alexandria), a chairman of the Draft Trible committee, said Trible "must indicate within four or six months" whether he is interested in running. By then, Mitchell and the other chairman, Del. S. Vance R. Wilkins Jr. (R-Amherst), said they hope to have $500,000 in cash or pledges to show Trible that financial as well as political support is available.

"I am truly flattered . . . {and} will seriously consider the breadth and depth of support . . . of those who want me to run for governor in 1989," Trible said in a statement from his Washington office.

After raising more than $1 million for a reelection campaign to the Senate, Trible announced last September that he would not seek reelection, saying he had been frustrated in Congress and wanted to spend more time with his family.

Wilkins said two likely Democratic candidates, Lt. Gov. L. Douglas Wilder and Attorney General Mary Sue Terry, "are having fund-raisers or putting together campaign organizations," and the GOP must do likewise, because "you can't do that between June and November in '89."

Mitchell, a moderate, and Wilkins, a conservative, represent the ideological extremes in the party, but said they have joined forces because Trible represents the GOP's best opportunity to recapture the Statehouse, from which the party has been shut out for eight years. A Republican governor, Wilkins said, could veto actions of the Democratic-controlled legislature.

A Virginia governor cannot serve consecutive terms.

Committee members said their effort should not be construed as against anybody else who wants the nomination, but the GOP's two other most promiment potential contenders don't see it that way.

"After chickening out" of the Senate race this year in the face of a challenge by former Democratic governor Charles S. Robb, "he {Trible} has got a lot of nerve," said Mark Strand, a spokesman for Rep. Stan Parris (R-Va.).

Parris is seeking reelection to Congress from the 8th District in Northern Virginia this year, but is considered likely to seek the governorship next year.

"People in the party are angry," said Dennis Peterson, executive director of Friends of Marshall Coleman, a committee backing the former attorney general and the party's 1981 gubernatorial nominee.

Peterson said the Coleman organization was formed "before Paul conceded the {Senate} nomination," and has raised about $220,000.

Mitchell said he and Wilkins believe Trible would have been reelected to the Senate and that he did not withdraw out of fear of losing to Robb.
