New Jersey’s new Democratic governor, Phil Murphy, wants to move his state back to the future — or, more accurately, to the past.

The dismal past, that is, of such predecessors as Jim Florio, Jim McGreevey and Jon Corzine — who unleashed the fiscal woes that have left the Garden State’s economy in tatters and its taxes sky-high.

That’s the takeaway from Murphy’s inaugural address last week, with his vow to produce “the state that leads the nation in progressive policies” and a laundry list of hard-left priorities that surely thrilled the hearts of every Democratic activist and public-union leader in the house.

He promised pot legalization, a $15 minimum wage, “equal pay for equal work” laws, automatic and same-day voter registration, a new state Office of Immigrant Defensive Protection, action to make the rich “pay their fair share in taxes” and, of course, resolution to “stand our ground” resisting President Trump.

(It’ll be interesting to see how he squares that with asking Washington for help funding new Hudson River rail tunnels.)

Among the things Murphy never did mention were answers for the state’s ongoing crises — like pension reform, lowering property taxes, cutting state spending or making Jersey more business-friendly.

As we noted last week, his first real decision is whether to devote all new tax dollars to the state’s ailing pension funds — or to let them head to collapse.

But Murphy — like so many New Jersey Democratic governors before him — is promising Garden Staters they can have their cake and eat it, too. And that they no longer need suffer the supposed austerities of the Chris Christie years.

We’ll see if the former Goldman Sachs financier keeps singing from the same liberal hymn book once the bills come due.

But if recent history is any indication, New Jerseyans may soon learn the age-old truth of what’s long been known as Murphy’s Law: Anything that possibly can go wrong, will go wrong.
