Platner’s long road ahead shows how Democrats may have fumbled the bag in Maine The Democratic establishment’s early bet on Janet Mills, as its best hope to pick up a coveted Senate seat in Maine, now looks like a clear miscalculation – one that has left the party boxed into a far riskier general election fight than it ever anticipated. By rallying behind the septuagenarian governor, and sidelining Graham Platner for months, party leaders helped create the very predicament they face. Platner’s primary victory on Tuesday now means the closely-watched race will be a test of fortitude for Democrats in the long road to November.
