Will Democrat Graham Platner Withdraw From Maine Senate Race?

Jessica Taylor of the Cook Political Report discusses two 2026 Senate primary dynamics: Graham Plattner’s endangered campaign in Maine and Mallory McMorrow’s exit in Michigan, along with the potential fallout for control of the Senate. - Graham Plattner faces pressure to withdraw from the Maine Senate race after new allegations, with a deadline of Monday for Democrats to replace him. - Maine is viewed as the top pickup opportunity for Democrats given Collins' weaker ratings and the state's presidential voting history. - National Democrats consider Maine essential to their path to a Senate majority. - Potential replacement candidates for Maine include former state health director Nirav Shah, ex-Senate President Troy Jackson, and others. - In Michigan, Mallory McMorrow dropped out of the Democratic primary, sharpening the race between Haley Stevens and Abdul El-Sayed. - National Republicans prefer to face the more progressive El-Sayed, while establishment Democrats back Stevens as the stronger general election candidate. - Mitch McConnell's hospitalization raises questions about a possible special election in Kentucky if a vacancy occurs before early August.
