The upset-minded campaign of Alexandria Mayor James P. Moran Jr. continued to outpace the fund-raising of Rep. Stan Parris (R-Va.) in one of this year's tightest, nastiest and most expensive election contests.

In the region's other closely contested congressional race, Rep. Roy P. Dyson (D-Md.) relied heavily on contributions from labor unions to maintain a fund-raising lead over Republican challenger Wayne T. Gilchrest.

According to campaign officials and finance reports due yesterday at the Federal Election Commission, Moran has raised about $79,000 more than Parris this year, but the two have about the same amount of money on hand as the Nov. 6 election nears. The finance reports are the last to be filed before the election.

A spokeswoman for Moran said he has raised about $698,000 this year and has roughly $165,000 in cash on hand. Parris has raised about $619,000 and has $160,000 remaining, according to his campaign finaince report. Moran raised about $118,000 between Oct. 1 and Oct. 17, the period covered by the current report, compared with $77,000 for Parris.

Randy Hinnaman, campaign manager for Parris, said that combined with contributions from last year, Parris has raised about $748,000. "We always expected to spend at least dollar-for-dollar with Mayor Moran, and we will," Hinnaman said.

In Maryland's 1st Congressional District, covering the Eastern Shore and Southern Maryland, Dyson reported raising $79,000 between Oct. 1 and Oct. 17, compared with about $44,000 for Gilchrest.

The five-term incumbent also had more than $70,000 remaining, nearly three times as much as Gilchrest.

A spokesman for Gilchrest, Tony Caliguiri, said three Cabinet secretaries are expected to make fund-raising trips into the district on Gilchrest's behalf, and the National Republican Congressional Committee promises to spend as much as $40,000 on direct mail and other campaign services for him.

But Dyson has also lived up to his reputation as a prodigious fund-raiser. He has collected more than $650,000, much of it from political action committees associated with defense and agiculture. More recently he has turned to labor unions, tapping them for about half of the money raised between Oct. 1 and Oct. 17.

Officials for both the Parris and Moran campaigns promised to continue running hard-hitting television ads through Election Day.

Hinnaman said the Parris camp will spend at least $150,000 on television ads in the final eight days of the race, while Moran's campaign manager, Mane Reiley, said the campaign expects to spend about $110,000 a week for television in the final three weeks.

Elsewhere, in Virginia's 10th Congressional District, Rep. Frank R. Wolf (R) has raised about $392,000 this year and has about $204,000 in cash on hand. Democrat N. MacKenzie Canter III has raised about $72,000, including a $23,000 loan from himself, and has $13,000 on hand. His campaign is planning to return a $5,000 loan that violates federal limits on campaign contributions.

Lyndon H. LaRouche Jr., who is running a campaign from prison, has raised a total of $546,875 (including $389,000 since Jan. 1) and has about $25,000 on hand, a spokeswoman said.

In Virginia's 7th Congressional District, Rep. D. French Slaughter (R) has raised $355,000 and has about $182,000 in cash on hand, while his Democratic challenger, David M. Smith, has collected $299,000 this year, with $42,000 remaining.

In Maryland, Rep. Tom McMillen (D) reported raising $332,000 so far this year. He has raised a total of $678,000 over the last two years and has almost $400,000 in the bank. His contributions from political action committees totaled $373,000. GOP candidate Robert Duckworth recently reported raising about $28,000 in that 4th District race.

In the 8th District, which encompasses much of Montgomery County, Rep. Constance A. Morella (R) reported raising more than $264,000 this year, and retains $228,000 in the bank. She faces Democrat James Walker Jr., whose report was unavailable.

As of Sept. 30, Rep. Steny Hoyer (D) had collected $291,000 from political action committees toward his $508,000 total in his race for reelection in the 5th District in Prince George's County. His opponent, Lee Bruer, has raised $7,340.
