BOSTON (AP) ? Republican U.S. Sen. Scott Brown’s campaign spent about $37 million on his unsuccessful re-election bid, but finished the race with a small surplus.

That’s according to a summary of a campaign finance report being filed Friday with the Federal Election Commission.

Brown finished with $464,000 cash on hand at the end of the reporting period on Nov. 26, but the campaign said about $150,000 to $200,000 would actually be left after some final bills are paid.

The campaign raised about $28.5 million during the election cycle. The expenditures include funds carried over from his previous campaign in 2010.

Brown was defeated by Democrat Elizabeth Warren after the most expensive political race in state history.

Warren’s campaign raised about $42 million but said earlier this week that it had a $400,000 debt.
