Former President Barack Obama is not following the path walked by most of our country’s ex-presidents.

Once they’re gone from the Oval Office, most former chief executives tend to fade away — some more than others — into the historical landscape.

Sure, they may not always move far from the political epicenter of Washington, D.C., and they definitely reappear from time to time as circumstances warrant. The nation expects that.

But the physical distance from the nation’s capital matters less than the actions they take and the demeanor they strike after they depart from 1600 Pennsylvania Avenue — especially as it pertains to the current and democratically elected occupant of the White House.

Many former presidents embark on humanitarian work they deeply believe in, or they attend events as dignitaries. Many write books, consult, give lectures and make appearances — and some even throw out ceremonial first pitches here and there.

Not former President Barack Obama.

The 44th president has been active, vocal and visible since he left the White House.

He’s not only been stumping for Democrat candidates and hosting rallies in states such as Texas, Nevada and California this year — he’s also been going out of his way to put down the current sitting president and has even taken credit for some of his successes. And his wife, Michelle Obama, has been holding a series of voter rallies this fall.

In his new book, “Trump Aftershock: The President’s Seismic Impact on Culture and Faith in America,” best-selling author Stephen E. Strang describes Barack Obama’s “stay behind” network — and reveals why he is still in Washington attempting to undermine the Trump presidency.

“Most presidents fade into the woodwork — this is presidential protocol,” Strang said in a statement ahead of his book’s publication on Nov. 6, 2018.

“George W. Bush and all his predecessors did that, but Obama wanted to have a third term and actually floated the idea. But I guess he figured out that two-thirds wouldn’t be willing to change the Constitution so he could stay in office. Instead, he set up shop in Washington, D.C., and he’s doing everything he can to keep things stirred up.”

Strang said: “Much of [this] is below the radar, so he isn’t blasted for it, but as I speak, he’s on the campaign trail endorsing Democrat candidates known to be socialists. Who would have thought that a socialist would ever be elected in America? It’s a scary day — and the Left is going further and further Left.”

“Donald Trump is very strong, but he can’t do it alone. We need to give him a House and Senate that will actually back the things he’s trying to do.”

Strang, who is also the author of “God and Donald Trump,” believes that “Democrats are shooting themselves in the foot with this tactic. Regardless, it’s scary for America, because the pendulum tends to swing from one party to the other. And if these socialists get into power, eventually the Democrats will have the White House again and one or both houses of Congress. That is why,” he adds, “I’m encouraging people who are like-minded to get out and vote. Donald Trump is very strong — but he can’t do it alone. We need to give him a House and Senate that will actually back the things he’s trying to do.”

The Strang book helps readers understand what the nation’s most unconventional president has accomplished thus far. A featured section is called “500 Days of American Greatness.”
