AUGUSTA — Fundraising in Maine’s U.S. Senate race has picked up since the end of May, and independent former Gov. Angus King continues to outpace his rivals in the race to replace outgoing Maine Sen. Olympia Snowe.

Campaign finance reports for the most recent fundraising period, May 24 to June 30, show King took in $468,000 in contributions from individuals and political action committees. That figure brings his fundraising total to $897,000 since he started his campaign in March.

Campaigns faced a July 15 deadline for submitting campaign finance reports to the Secretary of the Senate, which are later made available through the Federal Election Commission.

Secretary of State Charlie Summers attracted $149,000 in contributions for his Senate bid during the same five-week period, bringing his total to $239,000 since he entered the six-way contest for the Republican nomination in March. Summers’ campaign said $122,000 in contributions came in during the two weeks following Summers’ victory in that six-way primary last month.

State Sen. Cynthia Dill, the Democratic nominee, raised $66,000 during the second quarter of 2012, bringing her fundraising total to $91,000 since the start of her campaign. Dill added about $48,000 to her campaign account in the weeks following her win in a four-way Democratic primary on June 12.

Dill’s campaign finance report covered fundraising between April 1 and June 30.
