Westchester has the chance to send a clear message in Tuesday’s special election for state Senate District 37: Say no to Albany business-as-usual by voting for Rye City Councilwoman Julie Killian.

A Republican and mother of five, Killian has worked as a chemical engineer, on Wall Street and as a small-businesswoman. On the Rye council, she’s proved to be a nonideological problem-solver.

That hands-on work in local government is the sort of experience the Legislature needs. By contrast, her opponent, Democrat Shelley Mayer, is something of an Albany lifer: She was a Senate staffer before winning an Assembly seat herself.

Indeed, she was chief counsel to the Senate Democrats when they last controlled that chamber under Sens. Malcolm Smith and John Sampson (who were both later convicted of serious crimes). And she now faces charges that as chief counsel she was slow to act on harassment complaints.

Killian has been outspoken about ending Albany’s culture of pay-to-play corruption and sexual harassment. She also wants the state cap on property-tax hikes made permanent and favors rollback of the onerous regulations and high taxes choking New York.

A Mayer victory would make Democrats the theoretical majority in the Senate — except that Brooklyn’s Simcha Felder caucuses with the GOP.

Gov. Andrew Cuomo, busy rushing left to hold off Cynthia Nixon’s progressive challenge, is pushing hard to win this race and force Felder into line, so that a Democratic Senate can push through a Nixonesque agenda in the remainder of the legislative session.

Westchester would be far better served by sending an outsider to Albany — which badly needs shaking up.
