Incumbent Gov. Janet Mills, a Democrat, has paid $3.8 million to a Chicago-based firm overseeing her advertising production and placement, although the campaign says most of that money came back to Maine to pay for television, cable and radio ads.
This year’s campaign cycle has reached $23 million, a record for the state’s gubernatorial race. About 90 percent and 40 percent of incumbent Janet Mills’ and Paul LePage’s spending, respectively, have gone to out-of-state vendors.
