HANOVER, N.H. -- Although it is far from the much bigger communities of southern New Hampshire, the biggest contributor to presidential campaigns is Hanover.

The town of about 9,400 gave $20,800 through September, according to a report released by the watchdog group New Hampshire Citizens Alliance. About 30 residents gave it all, according to the Federal Election Commission.

The amount is more than double the contributions made by the state's two largest cities, Manchester, $8,850, and Nashua, $7,720.

Democratic hopeful Bill Bradley received $9,900 from Hanover residents and Republican George W. Bush received $7,000. Vice President Al Gore received $2,900 and Sen. John McCain received $1,000.

Aside from Hanover's relative wealth, one possible explanation for its generous giving is residents' interest in politics. Dartmouth College is located in the town, and was the host for the first presidential debates in October.

The New Hampshire study is part of a nationwide analysis conducted by Public Campaign, a campaign finance reform group based in Washington, D.C. It drew data from the 1990 census and the FEC and only includes contributions between $200 and $1,000. Contributions of $200 or more account for 84 percent of all contributions, according to Public Campaign.

Titled "White Gold: The Zip Codes That Matter Most To The Presidential Candidates," the report showed "wealthy and white" residents of communities, such as the upper east side of Manhattan in New York City; Beverly Hills, Calif.; Dallas, and Greenwich, Conn., gave large amounts, while poorer, more diverse areas gave substantially less.

Overall, large donors in New Hampshire gave $260,860.
