From the Morning Memo:

The Nassau County executive race continues to focus largely on ethics reform, with both sides trying desperately to tie the other to a number of scandals that have dogged their respective political parties in recent years.

Exhibit A: The latest TV ad – number three of the race, according to her campaign – released by Democrat Laura Curran, a Nassau County legislator.

The spot hammers Curran’s Republican opponent, ex-Sen. Jack Martins, for initially defending former Senate Majority Leader Dean Skelos in the wake of the federal corruption charges that eventually forced him from office.

The ad features footage of Martins demanding in the Senate chamber that Democratic colleagues trying to oust Skelos immediately after his arrest “please sit down.”

That was just part of a very heated exchange between Martins and Deputy Senate Minority Leader Mike Gianaris, who shouted at and over one another until the Democrats, after failing to force a vote on Skelos’ leadership, walked out of the chamber, en masse.

Curran also appears on the ad, saying that New Yorkers are “all paying a corruption tax, we are paying for the patronage, we are paying for the nepotism.”

“I love Nassau County,” she concludes. “I know we can do better.”

Curran’s campaign could not or would not reveal any information about the size of the buy for this ad, or how long it will be running.

Martins, as you’ll recall, has been lambasting Curran for hiring a NYC-based consulting firm, BerlinRosen, that has longstanding ties to NYC Mayor Bill de Blasio, and played a key role in scandals involving his fundraising that were investigated but did not result in any charges.

The ethics issue has been a particular focus in this race due in large part to the fact that a corruption scandal has forced the current county executive, Republican Ed Mangano, not to seek re-election.

Mangano has pleaded not guilty to federal charges of receiving bribes and kickbacks from a local businessman in exchange for favors.
