Brought before a House inquisition, MIT professor and Obamacare architect Jonathan Gruber burbled a recantation of his beliefs about how that triumph of liberalism had been achieved.

Yet, something needs to be said in defense of Gruber.

For while he groveled and confessed to the sin of arrogance, what this Ivy League con artist boasted about rings true.

Here, Gruber explained, is how we got Obamacare passed:

“This bill was written in a tortured way to make sure [the Congressional Budget Office] did not score the mandate as taxes. If CBO scored the mandate as taxes, the bill dies. OK? …

“Lack of transparency is a huge political advantage. And basically, call it the stupidity of the American voter or whatever … that was really, really critical to get the thing to pass. Look, I wish … we could make it all transparent, but I’d rather have this law than not. …

“[I]f you had a law which explicitly said that healthy people pay in and sick people get money, it would not have passed.”

Call it the new candor. Yet, is Gruber not right on almost all counts?

The “tortured way” the bill was written led a narrowly divided Supreme Court to uphold the act. As for the “lack of transparency,” did not Speaker Pelosi, midwife to Obamacare, say, “We have to pass the bill so that you can find out what is in it.”

Under Obamacare, “healthy people pay in and sick people get money.” Is that not true? Is it not true that had Obama and his party been honest like Gruber — that this was another rob-Peter-to-pay-Paul wealth transfer scheme — Democrats could not have passed it?

“Look, I wish … we could make it all transparent,” said Gruber, “but I’d rather have this law than not.”

Gruber is saying that, though the selling of Obamacare required obfuscation and deceit, it was worth it! We got Obamacare!

Liberals are beating up on Gruber for spilling state secrets.

And what did Gruber do that Obama himself did not do?

For the most persuasive lie in selling Obamacare was the one Obama told again and again: “If you like your doctor, you can keep your doctor. If you like your health care plan, you can keep your health care plan.”

Indispensable to running the Big Con, said Jonathan, was “the stupidity of the American voter.”

Here Gruber was wrong. The American people are not lacking in intelligence, but they are trusting, often lacking in knowledge, and they do rely on elected representatives to read and understand those thousand-page bills in Congress. And their faith is often misplaced.

Bottom line: Gruber & Co. won; America lost. Though the nation did not discover how badly it had been swindled until Obamacare began to be implemented.

The victory of Obamacare raises a question addressed by this writer 40 years ago in “Conservative Votes, Liberal Victories.”

Why, even when conservatives win elections, does the nation continue to move inexorably leftward? As a friend from that era wrote me recently, other than our victory in the Cold War, what do we conservatives have to show for all of our political victories?

In the half century since 1964, the GOP won the White House in seven of 12 elections. Since 1994, the GOP has won more off-year elections than it has lost, including the major wins in 2010 and 2014.

Republican strength on Capitol Hill today rivals that of the 80th Congress of 1946, and the dominance the party enjoyed in the 1920s.

Yet, from past disappointments, current hopes and expectations are not high.

What is it that pushes the nation leftward even when conservatives win at the ballot box? The permanent powers and the deep state.

While there are conservative enclaves within the major media, they are few. Our mammoth bureaucracy — 22 million municipal, county, state and federal employees — has a vital interest in the preservation and growth of government.

Add up the beneficiaries of all social programs, and the number now approaches 100 million. They don’t tend to stay committed to folks who will take away what they have come to depend upon.

Higher education is dominated by tenured leftists and radicals. The Ivy League is “No Conservative Need Apply” country.

Our popular culture, from movies to music to TV, is dominated by the left. Conservatives in Hollywood meet in catacombs.

There are conservative judges and justices on the courts, but few counter-revolutionaries. The decisions that come down either advance or confirm decisions handed down half a century ago by the Warren Court.

Yet, as Herb Stein observed, “If something cannot go on forever, it will stop.” From Illinois to Puerto Rico to France, Italy and Greece, debt-ridden Western social welfare states seem to be coming to the end of the line.

Like the shepherd boy in Aesop’s fable, the right has often cried, “Wolf!” This time, the kid may be right.
