Election Day is only five days away, and some of the most exciting races will take place in the Hudson Valley.

There are a few key Senate races that could determine the balance of power in Albany.

Both sides are pumping millions into local races as Republicans fight tooth-and-nail to keep control of their last source of power.

Republican Terrence Murphy and Democrat Justin Wagner are battling it out for an open seat in the 40th District. In the 37th District, freshman Democrat George Latimer is up against Republican Joseph Dillon.

If the Democrats do win, they would control every branch of New York state government.

The magic number to follow on election night is 32, which represents the number of seats needed by either party to control the state Senate.
