Maine Democrats gather Saturday in Bangor to nominate a replacement for Graham Platner, who ended his Senate campaign after a rape allegation. The party aims to unseat Republican incumbent Susan Collins in a race critical to Democrats' hopes of netting four seats to regain Senate control.

Former Maine Senate President Troy Jackson is the front-runner. A fifth-generation logger, Jackson runs on an economic populist platform mirroring Platner's, supporting Medicare for All, taxing the ultra-wealthy, abolishing ICE, and ending military aid to Israel. He's evolved on abortion and LGBTQ rights, earning support from legislators like Stacy Brenner.

Jackson faces a steep climb with only 100 days until Nov. 3. Collins, a 30-year incumbent, holds $11 million cash on hand. Jackson's campaign reports $1 million raised, emphasizing grassroots momentum against billionaire-funded super PACs backing Collins.
