The New York Times reports on Hillary Clinton’s debate preparation. She has set out to analyze Donald Trump’s weaknesses (is there time to get through a fraction of them?) and get under his skin at the debates. (The hidden lead, by the way, is from Trump’s “Art of the Deal” co-writer, Tony Schwartz: “Trump has severe attention problems and simply cannot take in complex information.” Not anything we didn’t know, but still.) If anything, Clinton suffers from an overabundance of targets — Trump’s intellect, his business record, his wealth, his habitual lying and his racism. The trick is to exploit them deftly so that viewers can see how unfit he is.

One technique is to take him up on his word. He said he “regrets” certain things. Invite him to apologize to Judge Gonzalo Curiel or the Gold Star parents of Capt. Humayun Khan.

Another tactic is to press him on empty and unintelligible answers. Trump rarely completes a sentence or can articulate any level of detail about his proposals. (The attention problem at work, no doubt.) When Sen. Marco Rubio (R-Fla.) and CNN’s Dana Bash tag-teamed, forcing Trump to explain what was in his health-care plan, it became patently obvious that he had a whole lot of nothing to offer. She can certainly take a page from New Jersey Gov. Chris Christie’s book (used against Rubio) in pointing out that Trump repeats the same platitudes. Tell us, Donald, what’s your plan to reduce crime in Chicago? Have you ever sat down with law enforcement?

There are oodles of issues (such as the nuclear triad) about which Trump knows nothing. Challenge him to spell out his stance on net neutrality, the South China Sea and student loans. In other cases — the minimum wage, repayment of U.S. debt and immigration, of course — he has been all over the lot. Force him to pick a position and explain why he has said the opposite.

Trump hungers for acceptance and approval. When he boasts that women and minorities “love” him, Clinton should point out that he gets virtually no support from African Americans in many polls and less support from Hispanics and women than Mitt Romney did. No Donald, they don’t love you. They’re on to you.

Clinton can try exposing his lies, although endless fact-checking may not necessarily win the day. (She doesn’t want to come across as Miss Know-it-All, nor does she want to bank on voters’ insistence on accuracy from candidates.) Using this technique sparingly, however, Clinton can knock Trump off stride and undermine the premise of his idiotic pronouncements. No, our allies do contribute to our defense. No, Moammar Gaddafi was not a friend of America. Crime has decreased since the 1990s — just ask Rudy Giuliani.

Puncture his phony image of business acumen. She surely can list the failures: football, vodka, steaks, mortgages, airlines, Trump University, casinos, etc. She can point to his testimony under oath in 2007 confessing to exaggerating his wealth. She can skewer the phony claims he made about charitable giving — until The Post sniffed him out. She can challenge him to prove his wealth and generosity — by releasing his tax returns to a neutral third party. She can recount his antics (business bankruptcies, lawsuits, etc.) to avoid paying small-business people and employees.

Finally, she can needle him for vanity (e.g. masquerading as a PR man to boast of his affairs) and self-absorption in the face of tragedy (Orlando, Nykea Aldridge). Mock him for claiming his “sacrifice” was in getting rich (to match the Khans’ sacrifice) and his assertion that sleeping around was  his “personal Vietnam.” (In risking exposure to venereal disease, he once proclaimed, “I feel like a great and very brave soldier.”) Laughing at him may be the one response that drives him around the bend.

Clinton should not, however, expect the moderator to maintain control nor complain about Trump’s rule violations and rudeness (unless it is to compare him unfavorably to her nearly 2-year-old granddaughter). Let Trump whine and play the victim, as he surely will. After that, all that will be left for Clinton to say is “SAD!”
