AUGUSTA, Maine — Independent U.S. Senate candidate Angus King slightly outraised Republican rival Charlie Summers during the latest two-and-a-half week fundraising period, according to their campaigns.

King raised $387,000 between Oct. 1 and 17, which includes the money his campaign raised last week at a fundraiser hosted by New York Mayor Michael Bloomberg at his Manhattan home.

Summers raised $325,000 during the same period.

While Summers is starting to narrow the fundraising gap between himself and King as the Nov. 6 election approaches, King has raised more than twice what his Republican rival has.

King’s total fundraising now stands at nearly $2.5 million since the former governor entered the Senate race in March. Summers, Maine’s Secretary of State, has raised almost $1.1 million since the start of his candidacy.

Together, their fundraising figure is a fraction of the more than $5.7 million outside groups have spent on advertising and direct mail to influence the race.
