Democrats are expected to endorse Hamburg attorney Joseph Amodeo to challenge State Senator Mark Grisanti in the November election.
It's the latest addition to what is becoming a crowded field who want to oust the Republican Grisanti.
Charles Swanick already has the Conservative Party endorsement while Kenmore Mayor Patrick Mang may try to run on the Working Families Party line.
The Buffalo News reports former State Senator Alfred Coppola may also enter the race.
