While de Blasio was campaigning in Iowa, Cuomo and "Mayor Johnson" are rushing to restore power

The mayor of Blasio was in a union room of auto workers in Waterloo, Iowa, where he was campaigning for president when the lights went out in Manhattan.

"The restorations are underway and ConEd aims to restore ALL customers by midnight," he tweeted.

But while Hizzoner was tweeting about the fault from afarAnd rushing to find a plane to return to the city, his often enemy, Governor Cuomo, rushed to the emergency command center of the Upper West Side, where he planned to hold a press conference .

"I have been governor of New York for eight years," he said on television. "Meanwhile, I can count the number of times I have left the state on my fingers."

Meanwhile, wags on Twitter were anoint city council president Corey Johnson as de facto mayor.

"Power failure in Manhattan. Mayor @ BilldeBlasio / @ NYCMayor did not tweet about it, except for a retweet, "Yashar Ali quipped at New York Magazine.

"New York City Council President @CoreyinNYC tweeted the updates for 30 minutes."

Tweety Nicole Gelinas from Hell's Kitchen"Mayor Corey Johnson has done a tremendous job over the past five hours. We have no idea what this random guy does in Iowa, but good luck to him.

"@CoreyinNYC is the de facto mayor tonight," Michael Scotto from New York One.

The mayor said Saturday night by a spokesman that he was driving to Chicago, where he planned to take a plane on Sunday morning to return to New York.

"We need to have a system designed to handle the disruption and rather than domino, we have redundancy in the system so that it does not happen anymore," Cuomo told reporters at the press conference.

"We simply can not cope with a blackout of this magnitude in this city. It's too dangerous. The risk potential for public safety and chaos is too high. We simply can not have a system that does not work. It's as simple as that at the end of the day and that's what we're going to work on. "
