JACK DONAGHY may be able to handle Liz Lemon, but can he handle New York?

Alec Baldwin, the veteran actor and would-be politician who plays Donaghy on "30 Rock," is thinking about running for mayor of the Big Apple.

U.S. Rep. Anthony Weiner was a favorite to replace Michael Bloomberg in 2013, but Weiner's likely candidacy took a bit of a hit this week - now that voters have seen his lever, it's unclear whether they'll want to pull it.

Enter Alec, a lifelong Democrat. A friend of Alec's told The Daily (website) that "Alec said 'Hey, maybe this changes the race. The dynamics have shifted.' The Democrats need a high-profile candidate and Alec can fill that bill."

But, but, but . . .

The only thing he's ever run is a fictional TV network. Alec later Tweeted, "It's a long way until November of 2013."

Before Alec does anything, he's going to have to fix one little problem - he needs to register to vote in the city.

According to the London Telegraph of all papers, Alec is a voter in Suffolk County, Long Island, where he has a home.

If he runs, he'll most likely change his primary address to Manhattan, where he has an apartment.

Getting a taste of how unpleasant politics can be, Alec wrote about Weiner on the Huffington Post, saying that Weinergate was an unfortunate byproduct of technology and life in the fishbowl.

Many readers took umbrage with Alec's comments, which prompted two Tweets: 1) "What I have offered on HuffPo is an explanation of, not an excuse for Weiner's behavior. Big difference." 2) "A lot, a real lot, of sanctimonious d-bags on HuffPo."

Alec, who was embroiled in scandal by his own angry phone message a few years ago, wrote, "My thought on Weiner is that he is a very busy man. Like most, although not all, politicians, he probably spends a great deal of time going to meetings, raising campaign funds and seizing upon every opportunity to remind people of how great he is as a public servant and a human being. It's exhausting. He exists under a constant pressure cooker of self-analysis and public appraisal. Like other politicians, he needs something to take the edge off. For some people, regardless of occupation, that could mean booze, drugs, gambling, food or shopping. For high-functioning men like Weiner and other officials who have lived through such scandals, who are constantly on the go, that leaves one tried and true source of a reliable high. The affirmation that comes when someone lets you know they want to sleep with you. Or even cyber-sleep with you."

And while much of what Alec said about Weiner and men of his ilk is true, it's also true about millions of other people - and not just famous actors and athletes who also suffer from the same drive that afflicts Weiner.

The problem, however, isn't the pressure; it's that all these people are egomaniacs. They're drawn to the pressure like bees to honey. It's the pressure that gives them the high - and trying to not get caught just adds to the pressure.

Is a congressman - with his big staff, nice salary, great health benefits and pension - really under more pressure than an unemployed worker who can't feed his or her family? Is a multimillionaire athlete under more pressure than a factory worker petrified every day that his/her job is going to be downsized to China?

The Weiners of the world cheat because they can - because they have big, charismatic personalities and there are always fame whores willing to give or sell themselves - and because they think that the world revolves around them.

Yes, they have tough jobs and lots of stress. So do a lot of regular folks who have none of their perks.

 * In Miami Beach, a large crowd pleaded with officers to release rapper Flo Rida (a/k/a Tramar Dillard), and one fan offered to drive him home, after he was charged with driving under the influence early yesterday.

According to an arrest report, officers spotted his 2008 Bugatti driving erratically about 3:45 a.m. The report said the rapper failed a field sobriety test - by a lot - had bloodshot, watery eyes and slurred his speech.

According to the Miami Beach police, after his second attempt at trying to walk a straight line, Flo said, " 'Officers, I can't do this. I don't feel I can walk a straight line. I had a few drinks. Let's try another test.' "

Like what, the SATs?

Flo was charged with DUI and driving with a suspended license after failing to pay a traffic ticket. He was later released on $2,000 bail, and a judge signed an order allowing him to fly last night to Bangkok to perform. Flo has to be back by June 16.

* Shania Twain's stumble during the CMT Music Awards show is being edited out of replays to save her from more embarrassment. Twain slipped and fell on her way to the stage Wednesday night during a live telecast. CMT left the spill out of a replay following the show and during another replay yesterday. Although CMT edited out the fall, footage of it aired on cable news channels and was available on the Internet.

So, editing out the footage really served only to call attention to it.

* Kelly Osbourne Tweeted recently that someone had been texting porn to her mother, Sharon Osbourne. Congressman Weiner, really! Sharon knows "America's Got Talent."
