Mayor Michael Bloom-berg cast his ballot Tuesday but remained mute on whom he was voting for -- as he's done throughout the election cycle.

The mayor, a resident of the Upper East Side, emerged from his 81st Street polling site around 7:50 a.m. and briefly took questions from the press.

He offered a full-throated endorsement of the voting process, but declined to reveal any specific information about his decisions inside the ballot booth.

Bloomberg's main goal, he said, is for the transition of power to go as smoothly as possible.

"I want to work with whoever wins and that's my responsibility," he said. "We'll do everything we can to make the transition be the best transition that any administration has ever done."

The mayor said that if he were to have endorsed a candidate it would have come earlier in the campaign season.

Asked by one reporter to weigh in on whether he was discouraged by Democratic candidate Bill de Blasio's plans to chart a different direction for the city if he wins, Bloomberg again reiterated that he hasn't been paying close attention to the race.

"I didn't see most of the ads. The real issue is not what they said during the campaigns. The real issue is what do they do once they're elected," Bloomberg said.

While holding strong on his decision not to endorse a candidate, Bloomberg did have a message for the voters.

"If you don't vote, you don't have any right to complain as far as I'm concerned," he said. "No excuses. The weather couldn't be nicer and there are clear choices."
