The fundraising surge was powered by out-of-state donations, according to the Bangor Daily News on Sunday.

Of the nearly $900,000 Collins received from individual donors contributing over $200, only $19,000 came from people with Maine addresses.

“We made an effort to have a strong quarter because we wanted to send the message that Senator Collins will be prepared to run a vigorous campaign in 2020,” said Amy Abbott, deputy treasurer of Collins’s campaign committee, according to the Daily News.

“We focused our fundraising efforts nationally, which we typically do until the election year, which is why there were relatively fewer donations from Maine.”

Her previous donation high was $1.2 million in the second quarter of 2007.

Collins received only $140,000 in the quarter before her vote on Kavanaugh.
