I'm going to bet over 80% of drug dealers in Maine are white.
Safe assumption, with the only risk of error being understatement. The worst thing that any drug dealer could do is to not fit into the ethnic mix. It is more likely that white dopers travel from Maine to visit black or Hispanic drug traffickers in Boston and then return with their poison than that black or Hispanic drug traffickers go to Maine where they would never be confused with black or Hispanic middle-class tourists visiting Maine for coastal scenery or lobster dinners.
