Maine Primary Countdown: Maine voters head to the polls Tuesday in closely watched ranked-choice races, with the U.S. Senate contest dominating attention as Democrat Graham Platner tries to win the nomination to face Sen. Susan Collins amid mounting allegations and a divided party response. Campaign Fallout: Democrats are split between backing Platner and demanding answers, as Rep. Ro Khanna argues there’s “no evidence of violence” while other lawmakers call the claims “beyond disturbing,” and Platner continues to tell supporters “Maine, you have my back.” Local Governance: Harrison residents vote Tuesday on whether to start the process of withdrawing from School Administrative District 17 to protect their local elementary school as consolidation pressures grow. Public Safety & Corrections: Somerset County will contract with Waldo County to share a jail administrator, a move aimed at saving money while changing oversight at the Madison facility. Cybersecurity: Meta says more than 20,000 Instagram accounts were compromised through an AI-powered account recovery tool, with Maine’s attorney general among those notified. Health Care Advocacy: A new open letter urges supporters to push for Medicare for All as a way to energize grassroots politics and counter authoritarian appeals.
