Alvin E. Thompson, the Democratic nominee for State Representive, filed a list of his contributors early Tuesday morning, after missing Monday's 5 p.m. deadline for reporting his campaign finances.

One set of forms, which the state Office of Campaign and Political Finance stamped at 9:16 a.m., reported campaign expenditures of $6140.54 and a surplus of $507.56 for the months of September and October.

But a second set of forms show that Thompson spent an additional $2674.54 raised independently from his campaign committee. The report does not indicate where he raised this money.

Thompson, a school truant officer and former assistant to the City Manager for community relations, defeated Democratic incumbent Saundra Graham by 49 votes in September's primary. Graham is running a write-in/sticker campaign against him to regain her seat.

Three unions contributed to Thompson's campaign: the National Association of Government Employees, the Alliance of MBTA Unions, and the Cambridge Teachers Federal Union. Individual contributors before the primary included School Committee member Donald A. Fantini, and former School Committee member David J. Holway.

Also among Thompson's contributors is Small Property Owners' Association President Peter Sheinfeld, who backs Proposition 1-2-3, a proposed 1989 municipal ballot question that would make it easier to remove apartments from rent control. In an interview two weeks ago, Thompson said he would not take a stand on Proposition 1-2-3 until he knew more about it.

Thompson also spent $750 consulting attorney Alec Gray on ways to monitor Graham's campaign. On Tuesday night he said he feared election officials might count ballots whose stickers had fallen off, and that there might be "violence at the polls" as a result of Graham's campaign.

A spokesperson for the campaign finance office said he could not comment on whether the office would take anyaction against late filers. Although Director ofCampaign and Political Finance Mary F. McTiguesaid Monday that Thompson's campaign probablywould not face penalties, she recently sent aletter to all candidates for state office,including Thompson, promising a crackdown on latefilers.

"Please be aware that this office has changedits policy with reference to late filers," theletter read. "We will no longer offer graceperiods to late filers before referring them tothe Attorney General for appropriate action."
