PORTLAND, Maine (AP) - A state senator and former Cumberland County sheriff says he's joining the expanding field of Democrats that is vying to become the party's nominee in the 2018 race for Maine governor.
Mark Dion, 62, of Portland, is joining the race. Whether Dion would run was a source of speculation for months. He's joining a group of 10 Democrats that is running in the primary next June.
Other Democratic candidates include Maine Attorney General Janet Mills and former Speaker of the House Mark Eves. Several Republicans are also running, and Republican U.S. Sen. Susan Collins says she will decide on Friday if she's running.
Dion was first elected to the Maine House of Representatives in 2010. He served three terms before his election to the Senate.
