Mike Tipping won the Democratic primary for Senate District 8 on Tuesday, defeating Abe Furth to advance to the general election for the newly drawn seat spanning from Orono to Prentiss where Democrats will be favored in the fall. Furth, the co-owner of Orono Brewing Co., said Wednesday morning that he would be conceding to Tipping, who led with 62 percent of the vote in unofficial results reported to the Bangor Daily News.
