Actually, only four Chapter 11 bankruptcies were official, but in some cases he just turned over the failed enterprise to his creditors, without going through the bankruptcy process (examples below).
It's not surprising that Trump is using rehashed liberal opinion hit pieces (like in Fortune and NYT) and liberal academics like Sonnenfeld who have vested interest, to attack Carly's business record (do I hear echoes of 2012's "attack from the left"?)...
He wants to deflect and divert attention from his own record of failures in many enterprises (e.g., Trump University, Trump Airlines / Trump Shuttle, Trump Magazine, Trump Vodka, Trump Mortgage etc., most of which ended up in debt defaults to creditors, or his Trump line of clothing which were manufactured in... China, Mexico and Bangladesh) and especially his former gaming empire built on nothing but his celebrity persona and pile of his high-interest expensive "junk-grade bonds" debt which he successfully offloaded it on unsuspecting shareholders in his public company Trump Entertainment Resorts, Inc. / Trump Hotels & Casino Resorts (DJT) after he bought-in his Trump Castle and later Trump Taj Mahal, while running the parent umbrella company through ownership of a separate (not common) controlling class of stock. That debt brought all 4 of the Trump casinos to bankruptcies, massive layoffs and loss of billions of dollars for shareholders and lenders who basically "invested in Trump's celebrity name and self-promoted aura of success" while he walked away with a pile of money from royalties (on his name), salaries and preferreds, and discharging his own debt...
Folks, stop rehashing the same opinion hit pieces based on superficial but deliberately incomplete or misconstrued "facts." Please read the actual facts in a few posts and links before you give credence to liberals, and ignore huuuuuuge problems with Trump's business record which will become huuuuuge issue in general election if he is the nominee, just because Trump (or someone else) is your candidate of choice. Nobody is asking you to renounce your candidate, or support Fiorina, but please stop spreading the liberal lies about her record at Lucent and HP - she didn't destroy either, and she saved HP from going into oblivion or obscurity like Kodak, Polaroid, Sun Microsystems, Xerox, Lexmark (former IBM printer division), Blackberry, etc.
Please, follow the links in these posts, so you won't have to ask the questions that have already been answered there - they will give you real facts, not opinions based on distortions and convenient omissions which would change the numbers and alter the picture (unless, of course you are so invested in your candidate and "destruction of Fiorina" that the "confirmation bias" would make it impossible) :

By contrast, here's some of Donald Trump's "magic" in his own words (Art of the Deal): "The final key to the way I promote, is bravado. I play to people's fantasies. People may not always think big themselves, but they can still get very excited by those who do. That's why a little hyperbole never hurts."

We were friends with the sister of the CEO of compaq and when compaq was sold to HP he seemed to think that Fiorina was an excellent business leader and was very friendly with her. I found it difficult to conceive that he could have been so flawed in his judgment.
I have to say also that I found Trump's remarks about Dr. Ben Carson not to be in accord with the realities of Dr. Carson's operation of his department at Hopkins. We were personally able to observe the operations there when the saved the life of one of our sons when our local hospital had the decency to recognize that they were over their heads. The description of running programs there as managing two nurses is extremely misleading.
And yet ‘Dumber than a Box of Rocks’ Boxer UTTERLY destroyed Fiorina with a few HP ads which Fiorina had NO answers for........we won’t even bring up HP sales to then sanctioned Iran because “What difference, at this point, does it make?”. Ya, she’d do well against whomever the Dims put up. Let’s hope Boxer doesn’t enter the race!!
