New York State holds it primary elections for statewide and state legislative offices on Tuesday, Sept. 9.  Below are the most hotly-contested primary races for State Senate seats in the Upstate region. (Next week, we’ll take a look at the state’s competitive Assembly primaries.)

S.D. 40 (Westchester/Putnam/Dutchess) – With incumbent Republican Greg Ball declining to run for office again in 2014, the Republican primary features Terrence Murphy and Bob Castelli.  Murphy is a chiropractor and restaurant owner who also serves on the Yorktown Council.  Castelli served two terms in the Assembly until he lost his re-election race in 2012. The winner of this race will face Democrat Justin Wagner in November.

S.D. 60 (Erie County) – There are Republican and Democratic primaries for this Senate seat.

Incumbent Republican Mark Grisanti is being challenged by attorney Kevin Stocker.

The winner will face either Marc Panepinto or Al Coppola, who are competing in the Democratic primary.   Panepinto is a practicing attorney; Coppola was a long-time Buffalo City Council member who briefly served in the State Senate.

S.D. 63 (Erie County) – In what is expected to be one of the most competitive primary races for the State Senate, incumbent Democrat Tim Kennedy is being challenged by County Legislator Betty Jean Grant.  This is a rematch of their 2012 primary race, in which Kennedy narrowly defeated Grant, despite having a massive financial advantage in the race.
