President-elect Donald Trump is doing his part to calm the waters as protests continue to roil (mostly) Blue America. Democratic leaders need to step up, too.

Starting with his Election Night victory speech, Trump has been calm, moderate and unifying. After one grumpy tweet about the protests, he followed with: “Love the fact that the small groups of protesters last night have passion for our great country. We will all come together and be proud!”

He’s also consistently signaling that hysteria is unnecessary. On Friday, for example, he said he’s hoping to keep the most popular parts of ObamaCare.

And Sunday night on “60 Minutes” he made it plain that the only illegal aliens he’s aiming to send home as soon as he takes office are those who’ve committed other serious crimes in this country — and he pointedly referred to most illegals as “terrific people.”

He also abandoned the “Muslim ban” long ago for a vow instead of “extreme vetting” of refugees from nations rife with terrorism.

Campaign rhetoric on both sides — and venomously pro-Clinton coverage in most of the media — often obscured a fundamental truth. Donald Trump is a practical man, and a lifelong New Yorker — not some hick bigot.

And shame on Sen. Harry Reid for blaring on post-election about Trump’s “grave sins” of “bigotry and hate”: Responsible leaders right now should be telling America to wait and see what the 45th president actually does.

His reported choice of GOP chairman Reince Priebus as White House chief of staff, for example, is a clear sign the crazies won’t be driving the ship.

We understand that many Americans, having been led to believe that Trump was a horrible ogre with no chance of winning, were shocked by his victory. Peaceful protest is a perfectly acceptable response, though we hope some will start realizing that The New York Times and its ilk may have been wrong on all counts.

We also know that it’s not Hillary Clinton voters pushing some protests into violence — but rather anarchist agitators who’ve plagued the nation’s far left for decades.

That said, we hope more Democratic leaders follow Clinton and President Obama in aiming to calm the waters — and in sitting on idiots like Harry Reid.
