This would be a good time to take one last swipe at soon-to-be departing Sen. Joe Lieberman.

But who could do better than MSNBC Keith Olbermann, who began his cable show by addressing Lieberman: "Don't let the delusional liar door hit you in the delusional liar butt on the delusional liar way out."

Gail Collins eviscerated the soon-to-be-former Connecticut senator on the editorial page of The New York Times this week, pushing many a reader to titters.

"Lieberman has reached a point in his public career when every single thing he does, including talking about his grandparents, is irritating," Collins wrote.

Indeed, why make fun of Lieberman any more, when soon we may have Linda McMahon and her steroid-hyped entertainment to kick around again.

The only irksome thing about Lieberman's not-so-gracious bow at center stage Wednesday is that we have barely recovered from the last wide-open Senate race, and it now looks like we are going to have to do it all over again - soon.

Freshly crowned Sen. Richard Blumenthal has barely gotten his Washington e-mail working, and already the power hungry are eying Lieberman's still-warm Senate seat.

U.S. Rep. Chris Murphy is in. Another familiar Democratic face, former Secretary of the State Susan Bysiewicz, who seems to at least have a Senate-sized ego, if not the qualifications of a senator, was the first to announce.

Among the mentioned are our own U.S. Rep. Joe Courtney, who may not, in the end, have an ego big enough to run for Senate, and some of the Republican wanna-be governors, former Lt. Gov. Michael Fedele and rich guy Tom Foley.

Former U.S. Rep. Rob Simmons of Stonington told a blogger for The Hill that he hasn't decided whether to get in again.

But it's clear from what he said that he is still bitter over losing the Republican nomination to McMahon last time around.

"Are we looking for a candidate who has actually won races? A person who's committed to public service?" he was quoted as asking. "Or are we still looking for a multi-millionaire?"

Ouch.

As for said multimillionaire, McMahon has certainly dropped plenty of hints, since losing to Blumenthal, that she might do it again.

I have to salute here the wisdom of Simmons, who suggested to the blogger, when asked about another McMahon candidacy: "Well, the definition of insanity is doing the same thing again and expecting a different result."

I would love to be a fly on the wall in the McMahon household when Linda proposes to husband Vince spending another $50 million on an unsuccessful Senate campaign. After all, $50 million for a Senate campaign here and $50 million there, and pretty soon you're talking about wasting real money.

Maybe she broached the topic while they were escaping the cold Connecticut winter in their Florida digs. Maybe they were out on their speedboat Sexy Bitch for a leisurely spin on the water.

If the Democrats choose Murphy, at least the race for Lieberman's seat will bring one fresh new face to the state's stage. Maybe the Republicans, too, will find someone new, a candidate who hasn't recently run a statewide campaign.

I'd almost prefer watching Lieberman drone on about how he could have won anyway - he could have learned a few things from Chris Dodd, who at least admitted in his retirement announcement to being in the "toughest political shape of my career" - than hear more about Linda's McMahon's one-time brush with poverty.

May all the dead wrestlers rest in peace.

And may the McMahons finally retire to a Florida tax haven for good and leave the rest of us here in Connecticut alone.

This is the opinion of David Collins.
