From the morning memo, the first item:

Insurgent Democratic primary challengers Zephyr Teachout and her running mate Tim Wu each picked up a pair of endorsements on Thursday, underscoring dissatisfaction within labor and the advocacy community over Gov. Andrew Cuomo.

Teachout was endorsed Thursday afternoon by the Public Employees Federation, a labor union of 54,000 mostly white-collar workers that has had an increasingly truculent relationship with Cuomo.

PEF endorsed Cuomo in 2010, hoping the move would give them an advantage at the bargaining table.

It didn’t work: Cuomo negotiated a less generous contract with PEF, similar to ones the administration negotiated with other major labor groups.

PEF ultimately accepted the contract under the threat of mass layoffs, but the simmering tensions resulted in Ken Brynien, the union’s president, losing his re-election to Susan Kent, who promised a tougher posture toward Cuomo.

Wu, meanwhile, was endorsed Thursday evening by the Village Independent Democrats, a political club that had initially endorsed Cuomo’s preferred running mate, former Rep. Kathy Hochul.

“There’s no better way to watch how things are changing than watching an endorsement change in real time,” Wu said in a statement. “That which seemed done is being undone; the winds of change are gathering and beginning to blow.”

Cuomo, keep in mind, continues to enjoy high marks among self-identified liberals: This week’s Siena poll found 75 percent of liberal voters give the governor a favorable rating.

But a first term marked by fiscal restraint — voluntary caps on spending at 2 percent, a willingness to not make perfect the enemy of the good on issues like public financing and an embrace of Republicans in the Legislature — has not offset for liberal advocates Cuomo’s socially progressive views on same-sex marriage and abortion.
