Maine Senate race tempers Democrats as Platner faces new scrutiny

Democrats in Maine are anxious as fresh allegations against Senate hopeful Graham Platner surface ahead of Tuesday’s primary, with some hoping Gov. Janet Mills could pull off a surprise upset or that Platner might drop out for a July convention replacement, while others warn any switch could deepen party divisions and threaten the effort to defeat Susan Collins in November; Platner denies the accusations and faces mixed support as late-May polls showed him well ahead of Mills, setting up a protest-vote dynamic in the primary.
