Republican U.S. Senate candidate Charlie Summers added $325,000 to his campaign bank account during the first two-and-a-half weeks of October, bringing his total fundraising to more than $1 million, his campaign says.

Summers raised his latest sum between Oct. 1 and Oct. 17. Figures from that reporting period are due in Washington, D.C., by Thursday. Independent candidate Angus King’s campaign hasn’t yet released the independent former governor’s fundraising totals for that period.

Summers’ $325,000 total for the first half of October follows news last week that he raised $507,000 in July, August and September, the first full fundraising period following his June victory in the Republican Senate primary. Summers, Maine’s Secretary of State, has now raised about $1.07 million since he entered the U.S. Senate race in March.

Even with Summers’ $325,000 early October gain, King still leads the fundraising race. His fundraising total as of Sept. 30 was almost $2.1 million, and that figure doesn’t include the money his campaign raised last week at a fundraiser hosted by New York Mayor Michael Bloomberg at his Manhattan home.

The total raised by the candidates’ campaigns is still a fraction of the more than $5.5 million outside groups have spent on ads and direct mail this campaign cycle.
