On the second day after the Orlando massacre, America’s president and his would-be successors performed to type. President Obama and Hillary Clinton still want it to be about banning guns and “countering extremism”; Donald Trump wants to face the facts about radical Islam.

Obama called the perp a case of “homegrown extremism” who’d been “inspired by various extremist information that was disseminated over the internet.”

No mention of the killer’s father, an Afghan immigrant who has praised the Taliban. Nor of the fact that (according to some of his ex-classmates) the young Omar Mateen cheered as the second plane hit the World Trade Center on 9/11.

Our president’s big takeaways: Do more on “countering this extremist ideology” (which he still won’t name) and “think about the risks” of “being so lax” on gun control.

Clinton provided a loud echo of Obama, denouncing “the virus that poisoned [the killer’s] mind” and demanding “the removal of ‘weapons of war’ from the streets.”

She talked up renewing the assault-weapons ban passed under her husband Bill in the ’90s, which lapsed last decade — without mentioning that FBI stats show the ban did nothing to reduce gun crime.

Oh, she had one good idea: Get the governments of Saudi Arabia, Qatar and Kuwait to stop letting their people finance extremists. So why didn’t she do anything about that when she was secretary of state?

Yes, she did announce one major flip-flop: Unlike Obama, Clinton finally agreed to say the words “radical Islamism” — a term she said last December she wouldn’t use for fear of somehow offending Muslims.

Trump, by contrast, slammed the nation’s “dysfunctional immigration system, which does not permit us to know who we let into our country,” nor “to protect our citizens.”

And he renewed his call to ban “immigration from areas of the world when there is a proven history of terrorism against the United States, Europe or our allies, until we understand how to end these threats.”

That would allow time to “develop a responsible immigration policy that serves the interests and values of America.”

And he gave full throat to what most Americans believe: “Many of the principles of radical Islam are incompatible with Western values and institutions. Radical Islam is anti-woman, anti-gay and anti-American.”

He cited an existing outrage: “Our own FBI director has admitted that we cannot effectively check the backgrounds of the people we are letting into America.”

And he mocked the idea that gun control can make a difference. (France’s tough gun laws certainly didn’t stop the Charlie Hebdo killers or the Bataclan Paris attackers.)

He closed with a promise: “When I am president, I pledge to protect and defend all Americans who live inside of our borders. Wherever they come from, wherever they were born, all Americans living here and following our laws will be protected.

“America will be a tolerant and open society. America will also be a safe society.”

It’s hard to quarrel with that.
