These squalid antics far too predictable

In local folklore union sentiment regarding neverending repairs to public projects such as Route 128 is captured in a slogan: Don’t kill the job!

Maybe it’s expressed differently in your line of work:

Don’t kill the goose that laid the golden egg. Don’t leave the gravy train.

Whatever it is, you get the point. When you’re in possession of a cash cow your instinct is to milk it as long as you can.

For shameless stewards of the once-proud Democratic Party that’s exactly what beleaguered Justice Brett Kavanaugh has become, a highly visible punching bag to be walloped whenever they please, resulting in an incessant pounding fueled by facts never established and charges never proven.

Let’s be serious. He’s a Republican, the personal choice of a GOP president; in other words, he’s red meat to ravenous Dems who clearly have not had their fill of him yet.

Having failed to foil his well-earned appointment to the U.S. Supreme Court, they now recklessly talk of removing him by impeachment if they manage to regain control of Congress in the upcoming midterm elections.

What else can you call that but a feeding frenzy?

He’s just too good to let go of, especially when there’s not much else on the menu. Unemployment’s down, factories are re-opening, despots around the world no longer thumb their noses at America’s armed forces; without Kavanaugh, what do Dems have to credibly bellyache about?

Funny, but when ex-Minnesota Sen. Al Franken had to step down because of moral turpitude (remember that infamous groping photo?), colleagues such as Amy Klobuchar, Mazie Hirono and Kirsten Gillebrand swapped teary-eyed embraces, hating to see him go.

When then-U.S. Rep. Barney Frank was exhibiting scandalous behavior three decades ago, even his principal cheerleader, the Boston Globe, held its nose, editorializing: “So far, Frank has enjoyed more than the benefit of the doubt; he has enjoyed a double standard.

“Frank has been talented in his public life and untalented in his private life; (his) career displays a chasm between the high ideals of his public life and the squalor of his private life. Barney Frank must go.”

Yet today Barney is once again an oft-quoted darling of the left.

It’s called redemption and it’s wonderful to see.

Ted Kennedy experienced it, too.

But in Kavanaugh’s case there’s no need for it because there’s no substantiated offense.

He simply remains a convenient chin to slug.

So shame on those who intend to keep swinging.

As the Globe might have put it, their antics are squalid.
