Democratic candidate for lieutenant governor Kathy Hochul assumed an attack dog role for Gov. Andrew Cuomo in her speech to convention delegates on Thursday, knocking Republican Rob Astorino for criticizing the state’s economic development efforts in western New York.

The speech, along with Hochul’s placement on the ticket, underscored Cuomo’s efforts to win western New York counties he lost in 2010 to Buffalo businessman Carl Paladino.

In speech debuting her as a statewide candidate, the former congresswoman seized on comments made by Astorino that questioned the effectiveness of the so-called “Buffalo Billion” investment by the state.

“It’s not the renaissance,” Astorino said in a gaggle with reporters last week. “It’s not what’s going to bring the state back, just throwing around tax dollars.”

Hochul equated the economic development program to icons of Buffalo like the Bills, Sabres and wings.

“He’s declared war on Buffalo,” she said of the Westchester County executive. “And I’ll tell you right now, If you want to mess with upstate New York, you’ve got to get through me and you’ve got to get through the governor.”

Hochul did not utter Astorino’s name in her speech, but accused him of running a negative campaign against Cuomo (state Democrats have already released a trio of ads knocking Astorino).

“It doesn’t fit into their narrative of negativity,” Hochul said of Astorino’s criticism of the Cuomo economic record. “It doesn’t fit into their narrative of negativity.”

Hochul’s nomination was made by both City Council Speaker Melissa Mark-Viverito and outgoing Lt. Gov. Bob Duffy.

The job of lieutenant governor is one of the less glamorous positions in state government, but Hochul in her speech said she’ll work with Cuomo as a team if elected.

“I’m so excited to work with our governor. We’re both fighters,” she said. “Together we’re going to be a team that elevates this state to new heights that has never, ever been seen before.”
