Maine: Paloma Partners

Ethan Strimling’s campaign has returned a $250 donation from a Connecticut hedge fund, saying it was given as a “dirty trick” by one of Chellie Pingree’s supporters.

Strimling and Pingree are both Democratic candidates in the 1st Congressional District race. Six Democrats and two Republicans are seeking the seat.

Pingree’s campaign said they know nothing of the donation, and public records searches show the fund’s founder had donated to Strimling’s interests in the past.
