From the Morning Memo:

Westchester County Executive George Latimer in a TV ad vouched for the candidacy of the woman who wants to replace him in the state Senate in what is seen as a pivotal battle for control of the chamber.

Latimer praised Democratic Assemblywoman Shelley Mayer in the ad, saying “Trump extremists” are spreading lies about her record in office.

“Shelley’s passed tough ethics laws and she’s fought to lower property taxes,” Latimer says.

Mayer, who appears alongside Latimer in the spot, says, “I don’t back down from bullies. In the state Senate, I’ll stand up for Westchester values.”

Mayer’s campaign on Sunday said the commercial was part of a significant ad purchase and will run through April 24, the date of the special election.

Mayer faces Republican Julie Killian for the Westchester County seat.

In addition to the TV spot, Planned Parenthood Empire State Acts is launching a digital ad campaign backing Mayer and calling for the passage of the Reproductive Health Act, a bill that is meant to codify the Roe v. Wade decision in state law.

The race is part of a broader fight over control of the state Senate, currently narrowly led by Republicans. A victory by Mayer would give Democrats 32 enrolled members in the Senate and a numeric majority. Control would flip to the Democrats if Sen. Simcha Felder, a Democrat who conferences with Republicans, flips sides.

Gov. Andrew Cuomo has come under pressure from liberals to help his party take control of the Senate after years of accusations that he preferred the arrangement of Republicans maintaining power with the help of the Independent Democratic Conference.

Cuomo brokered a deal earlier this month that would lead to the dissolution of the IDC and its lawmakers return to the mainline conference fold.

Still, Republicans are not giving up their last lever of power in New York state government without a fight.

Republicans have blasted Mayer for her handling of sexual harassment complaints during her time as Democratic counsel in the Senate that were leveled against a then-top aide in the chamber.

“Shelley Mayer has demonstrated an egregious pattern of choosing politics over the victims of sexual abuse,” said Killian spokeswoman Mollie Fullington. “And now she is making excuses and flat-out lying about these latest revelations. But this much is clear: Shelley Mayer does not support women when it is politically inexpedient. Her entire candidacy is built on a lie.”

Mayer’s campaign has maintained her role as counsel was not the proper channel to handle sexual harassment allegations.

Cuomo on Sunday, meanwhile, was expected to appear at a rally for Mayer in Westchester County at her campaign headquarters. Cuomo wound up not attending the event, but several cabinet commissioners appeared instead. A rally for Mayer with Cuomo is being considered for later in the week.
