CHICAGO  Little in Gov. Rod R. Blagojevich’s background prepared the people of Illinois for the man who was revealed in the criminal complaint that dropped like a bombshell here on Tuesday. Delusional, narcissistic, vengeful and profane, Mr. Blagojevich as portrayed by federal prosecutors shocked even his most ardent detractors.

“I almost fell over,” said Cindi Canary, executive director of the Illinois Campaign for Political Reform and a frequent critic of the governor. “I was speechless and sickened. In all of the millions of indictments I’ve read over the last years, I can’t remember anything as vile as this.”

Mike Jacobs, a Democratic state senator and former friend of the governor, suggested that Mr. Blagojevich may have lost his grip on reality.

“I’m not sure he’s playing with a full deck anymore,” Mr. Jacobs said. “I think he brought a lot of this on himself. He’s so gifted, but so flawed in a number of fundamental areas. It’s like he dared the feds to come get him.”
