"If Ms. Fiorina is what passes for conservative in Washington today, then the establishment has veered sadly to the left," writes Arianna Packard, grand daughter of David Packard, the co-founder of HP, in a letter RedState has obtained a copy of.Back at the turn of the 21st century, David Woodley Packard, the son of the founder, went to war against Carly Fiorina over the HP-Compaq merger. Vanity Fair documented the merger wars. It was not pretty. Both the Hewletts and the Packards opposed the merger.The bitterness from the merger wars lingers on. Ms. Packard's letter, written to Senators Inhofe, Coburn, and Kyl relating to their endorsement of Carly Fiorina, makes for interesting reading and signals that the heirs of HP intend to take her down. They lost once and they don't want to lose again."I know a little bit about Carly Fiorina, having watched her almost destroy the company my grandfather founded. So, allow me to disillusion you of a few of your stated reasons for supporting her," Ms. Packard writes before detailing, rather unflatteringly, Carly Fiorina's tenure at Hewlett-Packard.You can read the whole letter here. Game on in California. This comes on the heels of Carly Fiorina losing the California Republican Assembly's endorsement by a 2/3 vote despite receiving Coburn, Inhofe, and Kyl's letter supporting her.
