Fundraising efforts are under way to unseat Sen. Susan Collins, R-Maine, amid backlash over her decision to vote for Supreme Court nominee Brett Kavanaugh, who has faced allegations of sexual misconduct.

Be A Hero Team, Maine People’s Alliance, and Mainers for Accountable Leadership first launched a campaign in September asking for funds to go toward Collins’ opponent when she is up for reelection in 2020, in the event that Collins decided to back Kavanaugh. If she voted against him, all the funds would be refunded.
