Democrat Matt Dunlap says he will host the public launch for his 2012 U.S. Senate bid Saturday where he began his political career, a union hall in his hometown of Old Town.

Dunlap, a former Maine Secretary of State, is facing state Rep. Jon Hinck of Portland in the Democratic primary next year for the Senate seat held by GOP Sen. Olympia Snowe of Maine.
