She did get a classy jab in on the "Donald" at that... score 1 for Fiorina.
Trump highlighted her failure at HP (actually let her off the hook easy), a failure that already lost her one senate election against Barbara Boxer in California last year. Score 1 for Trump as well...
I called it a push between them...
I really think the business experience angle is a push between them. Trump's business ventures have under-performed compared to fairly modest investments that you could make. As for Fiorina, I remember her time at HP, which was contentious and objectively not very successful, and I'd largely forgotten about her after she got bounced out, and then when I heard she was running for president I was pretty surprised.
