SYRACUSE, N.Y. (WSYR-TV) — Dan’s guest this week on Newsmakers is John Mannion, who this week declared his candidacy for the Democratic nomination for State Senate in Central NY’s 50th district.  Mannion, head of the West Genesee Teachers Union, ran for the seat a year ago and narrowly lost to Republican Bob Antonacci. With Antonacci’s election to State Supreme Court, the seat will be vacant and a special election to fill the remainder of his term will likely be held in April.
