As a tech guy (going way back to the early 90s), who followed Fiorina closely, the idea that criticism of her tenure is revisionist history is laughable.
She was loudly and prominently panned in the IT world, especially after the Compaq merger - which was a total disaster.
CF lacks vision. For example, the PC market was very competitive when she led the merger with Compaq. Well, a couple of years later competitor IBM sold off it's PC business to Lenovo and exited the market.
Also, the Compaq/DEC merger was not fully settled (the two cultures never really gelled) when she made the move at HP to merge with Compaq. She does not have a good business mind, nor has vision.
As a politician, we have only her failed attempt at a senate race in CA. Not much to stand on really....business record not positive, political career not positive. Why should she be POTUS again?
