FOR MORE ON TRUMP, READ GELZINIS

How does Donald Trump get away with this stuff?

Even after sliming Fox News anchor Megyn Kelly with insults that would draw groans in just about any barroom, The Donald still leads a platoon of befuddled Republicans who would like to be president.

He has flouted every law of political gravity, not to mention GOP politics, and it’s kept him way, way out in front.

Other than Mayor Marty Walsh, there was no one around here who’s taken umbrage at Trump’s view of Mexicans as rapists and drug dealers.

Likewise, I don’t recall a significant local backlash when Trump, who escaped the Vietnam draft due to bone spurs in either his right or left foot (he can’t remember which), said Arizona Sen. John McCain’s years of torture inside the Hanoi Hilton did not make him a hero.

Trump prefers heroes like Sly Stallone and Bruce Willis, who never get captured.

Still, I figured that after this latest slimeball hurled by Trump, there would have to be a few local Republican women of stature who would put him in his place.

So, naturally, I thought of Lt. Gov. Karyn Polito, that spitfire from western Mass. I was certain she wouldn’t shy away from an opportunity to take a verbal jab at a guy running for the White House who’s gleefully called women slobs and fat pigs. I was wrong. When Polito was approached on the State House steps yesterday by a Herald videographer and asked to comment about Trump’s latest Archie Bunker-like remarks, the woman a heartbeat away from running this state had a twoword reply: “Not today.”

To be fair, Polito was soaking wet, after dumping a bucket of ice water over her head along with Charlie Baker and most of his staff. But, honestly, Karyn, a little cold water is a lousy excuse.

I reached out by phone and text to GOP state Rep. Shauna O’Connell, who has generated no small amount of heat over her crusades against EBT card fraud.

I was hoping she might jump at the chance to take a spirited whack at the goldplated New York huckster. But when the phone didn’t ring and the text didn’t show up, well …

Finally, I hoped Kirsten Hughes, chairwoman of the state GOP, would strike a blow on behalf of her besmirched sisters, but there was nothing save the deafening sound of silence.

It’s not the tycoon in Donald Trump, but rather the low-rent TV celeb who has figured us out.

He knows he can graft his churlish face onto a Republican Party that’s said nothing but no for the past 6 1⁄ years — and come away

2 looking like George Washington.
