Attorney Wendy Long has won a three-way Republican primary to take on Kirsten Gillibrand in this fall's race for the U.S. Senate.

Long defeated Nassau County comptroller George Maragos and U.S. Rep. Bob Turner in a primary election Tuesday notable for low turnout. Long held a double-digit lead with more than half the precincts reporting statewide.

Long now faces an uphill battle against Democrat Gillibrand, a three-year incumbent who already has about $10 million in campaign cash.

This will be Gillibrand's second campaign for the Senate since she was appointed in 2009 to replace Secretary of State Hillary Rodham Clinton. She won election in 2010 to finish Clinton's term that ends this year

This time, Gillibrand's running for a full, six-year term.
