The victors said it was too soon to talk of higher office, but at Tuesday night's Democratic victory party in New Carrollton, partisans were already chanting "Governor Glendening" and talking up State's Attorney Alex Williams as a potential successor to Prince George's County Executive Parris N. Glendening.

With his overwhelming election to an unprecedented third term while other area county executives lost or barely squeaked by, Glendening emerged from Tuesday's election as a strong regional prospect for governor in 1994.

And with his decisive reelection as state's attorney, Williams emerged as a leading candidate to succeed Glendening and become the first black county executive in Prince George's history.

"I think he really is the odds-on favorite if he were to run," said state Sen. Albert R. Wynn (D-Prince George's).

Tuesday's virtual Democratic sweep, which apparently included the leadership-backed write-in election of Stephen J. Del Giudice to the County Council, further demonstrated the dominance of the county party organization.

While insurgents such as newly elected Montgomery County Executive Neal Potter did well elsewhere, independent Democrats and Republicans failed to overcome traditional Democratic slate politics in the suburban county of 720,000.

Senate President Thomas V. Mike Miller Jr. (D-Prince George's) said the organization sweep shows that the party "is reaching out to all the various constituencies . . . . The lack of discontent indicates that {voters} are pleased with the quality of leadership."

Democrats hold a 3 to 1 registration lead over Republicans, a majority that Miller projected would increase as black population increases.

"You look at the demographics and Prince George's is not unlike Baltimore city," where the ratio is nine Democrats to one Republican, Miller said. "In Prince George's, it will be slow getting to that point, but, if current trends hold true, {the Democratic voters} will move up eventually."

The surge in Republican voters seen in many suburban counties surfaced only in the legislative district encompassing Laurel and southern Howard County. There, Republicans Martin G. Madden and John S. Morgan unseated Democratic delegates William C. Bevan and Robert J. DiPietro. The Republicans, who live in Howard, were the first of their party elected to represent Prince George's in the legislature in 40 years.

Otherwise, the Republicans had little to comfort them. Democrat-turned-Republican Arthur A. "Bud" Marshall Jr., mounting what Democrats considered their stiffest challenge, garnered 40 percent of the votes in his bid to regain the prosecutor's job he had held for 24 years. It was a contest that some Democrats viewed as having racial implications.

Marshall won by large majorities in predominantly white south county areas such as Tantallon, and in many Bowie and Laurel precincts. Williams's tallies were overwhelming in such inner Beltway communities as Seat Pleasant.

But Williams, savoring a victory that also transcended race, said, "We sent a strong message all over the entire Washington area that says in this county, we look at issues, we look at character, and we made decisions."

The number of black office holders increased only slightly in the county where blacks are becoming a majority, however.

Gloria Lawlah, running unopposed after defeating state Sen. Frank Komenda in the primary, became the third black among the county's eight state senators. And Frederick Hutchinson's victory made him the third black member on the nine-member county Board of Education.

Howard Stone Jr., the black first vice chairman of the Democratic Central Committee, said the Marshall-Williams race was "a strong test of whether racial politics was alive in Prince George's and the resouncing answer was no." However, he said, "The true test to see if multi-ethnic coalitions really work in this county" will come in 1994, when more blacks seek office.
