Republicans in St. Lawrence County will choose candidates Tuesday in the 115th and 116th Assembly Districts, while Democrats help choose candidates for governor and lieutenant governor to represent them on the ballot in the November general election.

Running for the 115th Assembly district, which includes Brasher, Hopkinton, Lawrence and Piercefield, are incumbent Janet L. Duprey and Karen Bisso.

Running for the 116th district are John S. Humphrey and John L. Byrne III. Although not a Republican party candidate, Russell Finley filed a “petition to ballot,” which allows registered Republicans to write in candidates. The 116th Assembly District is currently held by Democrat Addie Russell.

The district includes Canton, Ogdensburg, Massena, Potsdam, Lisbon Morristown, Depeyster, Hammond, Louisville, Oswegatchie, Rossie and Waddington.

Conservatives will also choose a candidate for the 116th district. Russell Finely is the only candidate on the ballot, but Conservative voters may also write in candidates, thanks for a successful petition to ballot by Republican John Byrne.

St. Lawrence County Democrats will help decide candidates for governor and lieutenant governor. Democrats in the race for governor are Andrew M. Cuomo, Zephyr R. Teachout and Randy A. Credico. Kathy C. Hochul and Timothy Wu are competing for lieutenant governor.

Polls are open from noon to 9 p.m.

Those who have not registered to vote with a party by now, or who have been registered but have moved within the county and have not notified the Board of Elections by now cannot vote in a primary.
