ALBANY — Not so long ago, the Four Amigos were the kings of Albany.

They were state senators from New York City, Democrats who threw the upper house of the Legislature into chaos after the 2008 election, at a time when Democrats should have been celebrating winning control of the chamber for the first time in more than four decades. Instead, the amigos — a term they bestowed upon themselves — gleefully posed before camera crews and loudly courted both sides of the aisle for perks, power and patronage.

Two of the amigos, Pedro Espada Jr. and Hiram Monserrate, even briefly allied with the Republican caucus in 2009, orchestrating a coup that for a time paralyzed the state government.

Ah, karma.

Now, two amigos — Mr. Monserrate and Carl Kruger — are headed to prison, and the fate of a third, Mr. Espada, is in the hands of a jury after a federal corruption trial. Jurors said Wednesday that they had reached an impasse, but the judge, Frederic Block, instructed them to continue deliberating.

Few of their fellow Democrats are sorry to see them gone from Albany.

“Three are gone,” Senator Liz Krueger, a Manhattan Democrat, said with a broad smile on Wednesday, before walking into the legislative chamber.
