Clinton would run as former first lady and major player in the highly successful Bill Clinton presidency; and as a former U.S. senator and secretary of State. Warren would run for vice president as the conscience of the Senate and the great champion of consumers and workers throughout America.
By contrast, Fiorina would run with the novelty of having fired and laid off more workers than any presidential candidate in history, and having mismanaged her business when CEO of Hewlett-Packard, before being unceremoniously removed from her post by a very unhappy board of directors. Palin would run for vice president as the former mayor of Wasilla, Alaska who then served for part of a one-term governorship of Alaska before leaving before her term was finished to make her mark in reality television.
There is a difference between Fiorina and Palin. I will confess to having a soft spot for Palin as a person. I suspect if I knew her, I would like her, which I mean as a compliment even though she is not appropriately credentialed to be president or vice president. Fiorina, by contrast, was cruel and heartless to her workers when she was CEO of Hewlett-Packard.
