Who's up and who's down this week?

To hear state Sen. Michael Gianaris tell it, his feud with state Sen. Jeff Klein was a petty matter that Klein just couldn’t get over. To his credit, Gianaris stepped aside for the good of the party to make way for Klein to take his No. 2 spot in the state Senate Democratic hierarchy when the Independent Democratic Conference was ended. Gianaris made clear he wasn’t backing Klein for re-election – and now that Klein is the latest establishment figure to be toppled by the progressive insurgency, Gianaris is poised to move back up the ladder – and enjoy the benefits of leadership.

Rep. Chris Collins announced that he would run for reelection after all, reversing an earlier decision to step aside following his indictment and arrest for alleged insider training. This plays into the hands of Democratic challenger Grand Island Town Supervisor Nate McMurray who might have seen his long-shot bid ruined if local county leaders had been able to replace Collins on the ballot with a less controversial candidate in the heavily Republican district. The Cook Political Report responded to Collins’ announcement by downgrading the GOP’s chances of holding onto the Western New York district from “likely” to “lean Republican, reflecting McMurray’s improving odds.

For some people, the third time’s the charm. For a politician like Hiram Monserrate, convicted of misdemeanor assault and having spent nearly two years in prison, it’s more like the fifth time. After four consecutive failed bids for public office, Monserrate prevailed last week and was elected district leader by Democrats in East Elmhurst, Queens. Demonstrating that you might win if you just keep showing up, Monserrate also helped deliver victories for his allies in nearby districts. Monserrate has said his troubled past of domestic violence and mail fraud is in his rearview mirror, and now, so is his losing streak.

The actress-turned-candidate won her court case over petition signatures to be on the ballot as an independent running against Republican Rep. John Faso and Democratic candidate Antonio Delgado in the 19th Congressional District. It’s a long shot for the first-time candidate, but she worked really hard to get here: Last month, the state Board of Elections almost ended her bid when it rejected almost half of her signatures and put her 1,171 signatures short of what she needed. Thanks to some Law & Order, she was able to challenge that call and the Supreme Court reversed the BOE’s decision.

The Bronx high school teacher became the first New York State Teacher of the Year from New York City in two decades. It’s not hard to see how Susso was able to distinguish himself from the other 200,000 candidates for the honor. A debilitating eye disease and impoverished childhood in his native Gambia taught him perseverance, a lesson he passes on to immigrant students at International Community High School. If a teacher “can get to their young minds and guide them, they can use that knowledge and skill to be able to lead meaningful lives,” he told the Daily News.

This top-ranking official at the state Office of Mental Health has been arrested. For what, you may ask? Considering this is New York, a first guess would likely be some kind of corruption. No, this is far skeevier. Allen been charged with 29 counts of child endangerment. To get into the shocking details, he is accused of luring teens into his house and asking them to wear diapers. Allen’s arrest can be chalked up as a win for all the teenagers in his general vicinity.

Old buddy Percoco will be in prison until Cuomo’s fourth term. And further disclosures about the state Democratic Party’s controversial mailer painting Cynthia Nixon as anti-Semitic continue to trickle out, as it appears that the governor’s inner circle knew about it. All Cuomo wanted to do after a landslide victory in the primary was to gloat, but the news made it tough – and those pesky prognosticators and pundits kept second-guessing his commitment to flipping the House.

For many New Yorkers, there are no greater evils than Goldman Sachs and the Boston Red Sox. And de Blasio met with both – at the same time! He may be a fan of the Sox, but even de Blasio must have realized how such a meeting would appear to his Yankee-loving, left-leaning base. It’s no wonder he chose to exclude it from his public schedule. Plus, de Blasio’s getting sued for not releasing information about subway fare beaters, which city is supposed to do by law. And on top of all that, public school busing is downright terrible. All in all, a banner week for Hizzoner.

The Republican Erie County chairman felt “like a jilted groom at the altar” after indicted Rep. Chris Collins decided to stick around and continue his re-election campaign. Langworthy and other Republican leaders had been developing a plan B since August, when the congressman was arrested on insider trading charges (and then allegedly lied to federal agents about it). Collins assured party leaders as recently as last week that he would cooperate with maneuvering to take him off of the ballot, but has apparently backtracked. It’s the state’s most heavily red district, but Collins’ announcement moved the meter from “Likely Republican” to “Lean Republican” – and left Langworthy with no choice but to stand by and watch.

A slew of domestic abuse allegations caught up to Cohoes Mayor Shawn Morse this weekend. Multiple elected officials, including Gov. Andrew Cuomo, have called on Morse to step down in the wake of abuse allegations by his wife and younger daughter, who detailed alleged actions like striking and choking them both. These allegations pile on top of similar ones made against Morse last year. Cuomo said the State Police had reopened an investigation of Morse’s conduct after the Times Union reported the new allegations. Morse, however, has doubled down on his denial and refuses to resign from office. Whether or not he eventually steps down, it’s clear Morse is facing a reckoning.
