ALBANY — Buffalo businessman Carl P. Paladino took his fledgling, anti-Albany gubernatorial campaign into the belly of the beast Tuesday, offering a menu of fiery, rhetorical flourishes against everyone from “corrupt” government officials to poor people trying to game the welfare system.

In his first appearance at the State Capitol since declaring his Republican candidacy Monday night, Paladino was short on specifics on several of his key proposals.

But with little prodding from reporters, he unleashed his attacks against his apparently favorite new target: State Attorney General Andrew M. Cuomo, expected Democratic gubernatorial candidate.

When he wasn’t bashing Assembly Speaker Sheldon Silver, Buffalo Mayor Byron W. Brown and everyone in between, the real estate developer labeled Cuomo the “initiator” of the nation’s subprime mortgage meltdown. He accused the attorney general of trying to “punish” businesses with his investigations while being soft on Albany corruption cases and said Cuomo’s expanding government pension probe is merely poll-driven.

As a capper, he said Cuomo’s real political ambitions do not stop with the governor’s office. “It’s a way station on the way to be president,” Paladino said.

“Because he is the entitled one. His daddy said, ‘You’re entitled,’ ” Paladino said of Cuomo and his father, former Gov. Mario M. Cuomo.

The millionaire businessman repeated criticisms of Silver, the Assembly’s longtime top Democrat, as embodiment of everything wrong with Albany and said that, as governor, he would force Silver to reveal his outside income from a Manhattan trial law firm. A Silver spokesman declined to comment.

Paladino went after Brown, calling him “ignorant” and said “any ideas with long words and big sentences are confusing to him.” State Sen. Antoine M. Thompson, D-Buffalo, is “of the same crop” as Brown, he said.

In a statement, the mayor said, “As always, his ramblings are nonsense, and I will not debate this hypocrite.”

Paladino, who acknowledged he is not “politically correct,” didn’t limit his rhetorical attacks to Democrats, beating up fellow Republicans, including newcomer Steve Levy, the Suffolk County executive, and Rick Lazio, the former Long Island congressman, both already running for the GOP nomination.

He even went back to the administration of former Gov. George E. Pataki, calling Charles A. Gargano, the state’s former economic development czar, a “breath of stale air” who treated upstate like “the backwoods.”

Douglas Muzzio, a political scientist at Baruch College, said Paladino is providing some “entertainment value in the short term,” but he risks becoming “an exploding cigar that vanishes.”

“It’s a way to make a splash,” Muzzio said. “And, he and his advisers clearly believe that there is an angry vote out there and that he’s the candidate of the angry voter.” But Muzzio said voters will want more. “Voters will take a look at him and say, ‘How will you deliver?’ ” he said, adding, “Anger is not a program.”

In a mere 50 minutes with reporters, Paladino made more stinging and pointed attacks on Cuomo — the Democrats’ presumptive nominee — than the two other Republicans in the race have combined.

As the nation’s housing secretary during the administration of former President Bill Clinton, Cuomo pressured lenders to give mortgages to people unable to afford them, Paladino said. “Andrew destroyed their lives. . . . It’s disgusting,” he said of a crisis that cost thousands of people their homes.

Cuomo, Paladino said, “did a terrible injustice to those poor Americans, telling them they could have a house they couldn’t afford,” and did “a more egregious injustice to the taxpayers and the people who had homes as he created the subprime meltdown, which resulted in lower valuations.”

Paladino accused Cuomo of pushing the mortgage agenda to help prop up the Clinton administration and “in the name of Andrew’s political career,” as well as to help “the liberal, if you want to call it, subpoverty people.”

He said Cuomo is interested in becoming governor only so he can run for president. Many Democrats believe Cuomo is eyeing a 2016 White House run.

He said Cuomo has tried to look tough with prosecutions on Wall Street. “But he can’t find any crime here in Albany?” Paladino said of corruption at the Capitol.

He went after Cuomo for not suing over the new health care law pushed by President Obama, as some other state attorneys general have done. If Paladino was hoping to draw Cuomo into a fight, it didn’t work. A spokesman for Cuomo declined to comment.

But Jay Jacobs, chairman of the State Democratic Party, called Paladino’s comments “irresponsible” and indicative of the “new bizarre world” of the GOP primary in which the three announced candidates “compete for the most inaccurate, absurd and offensive quote of the week.”

Paladino said he was not prepared yet to discuss the state budget and its $9.2 billion deficit. He also could not tell reporters what section of the State Constitution backed his claim that, as governor, he could declare a fiscal emergency and be given broad powers to control the budget. And he could not give specifics about one of his top target areas: welfare abuse.

Hoping to appeal to conservative voters in this blue state, Paladino said welfare programs permit people — “the poor and the lame and whatever” — to move into this state and automatically “hop onto” social programs, such as Medicaid. He could not say how many such people have done that.

From Albany, Paladino took his new campaign to Manhattan for a round of media sessions Tuesday night and this morning before heading to Syracuse tonight for an “Ask Carl” town hall meeting.
