Democrat Graham Platner, who is challenging GOP Sen. Susan Collins in Maine, is exporting Zohran Mamdani socialism to the state, a Republican leader says.

Graham Platner, a military vet and oysterman from a small town in Maine, will run for U.S. Senate as a Democrat in an effort to oust Republican Susan Collins.

Platner is the latest Democrat to announce his candidacy in the 2026 senate race against the incumbent Collins. Others include Jordan Woods, the former chief of staff to then-Rep. Katie Porter, and David Costello, who ran against Maine Independent Sen. Angus King in 2024.
