Democratic State Assemblyman Harry Bronson may be facing the toughest re-election campaign of his ten years in office.
Over the weekend, the Monroe County Democratic Committee endorsed challenger Alex Yudelson, instead of Bronson.
Yudelson is Mayor Lovely Warren's chief of staff, and served for two years in the Obama White House.
Bronson says the endorsement vote wasn't conducted fairly.
The two men will likely face off in a Democratic primary in June. The district includes parts of Rochester, Henrietta and Chili.
