AUGUSTA, Maine — A citizens’ activist group is calling for Charlie Summers to resign as Maine secretary of state, saying his serving poses a conflict of interest while he is running for U.S. Senate.

The secretary of state’s office administers Maine elections, and the Maine People’s Alliance says Summers should resign because of a conflict in overseeing his own election. Alliance Executive Director Jesse Graham says Summers should also resign because of his past action sending letters to college students about requirements for registering and voting.

A spokeswoman for Summers says he has turned over all elections oversight to a deputy secretary of state.

None of the six Maine secretaries of state or attorneys general who have run for higher office in the past 30 years resigned.
