New York Times: “The Democratic primary race for Senate in Maine is swiftly becoming a test of how liberal voters perceive risk and electability as their party searches for a path back to power.”“Trailing in public polls and fund-raising, Gov. Janet Mills of Maine, 78, has unleashed a barrage of scathing attack ads against Graham Platner, a 41-year-old oysterman and veteran, that highlight his online history of dismissive remarks about rape. His broader record of inflammatory comments online, Ms. Mills argues, could doom his chances in a general election against the battle-tested Senator Susan Collins.”“The stakes of the race, which has quickly become one of the most contentious Democratic primaries of the midterm season, could not be higher for the party.”
