I definitely agree that Carly Fiorina was a terrible CEO and is totally unqualified to be President. However, you could say the same thing about Trump:
Donald Trump filed for corporate bankruptcy five times, in 1991, 1992, 2004, 2009, and 2014. By 1990, Trump’s business skills had amassed debts of $4 billion, including $975 million he personally guaranteed. In 1991, unable to pay a $3.5 billion loan, he declared business bankruptcy. He was $900 million in personal debt, selling his Trump Princess yacht, his Trump Shuttle airline, and other investments.
The lesson he learned from this was to hide the risk of his business dealings behind the protection of corporate entities.
Trump sued Deutsche Bank to get out of a $40 million loan during the 2008 financial crisis saying it was a ‘act of God’.
In 2013, the New York State Attorney General Eric Schneiderman filed suit against Trump accusing him of defrauding more than 5,000 people of $40 million by promising to teach them his get-rich techniques at his “Trump University”–a ‘free introductory 90-minute presentation’ to build a real estate empire which was in fact an advert for a three-day, $1,500 seminar which offered people “elite” further seminars costing from $10,000 to $35,000.
