Calling your stepson your son is not really that big of a deal ... especially if the poor kid had been in your life for years and then died. You should be allowed to refer to him in any manner you desire.
As for the HP stuff, her version comports with what I was reading in the papers at the time. The HP board of directors really was akin to Romper Room in those days ... worthy of a television reality show at the time ... and in hindsight, her decisions seem to have paid off for the company.
Trump is a slick/cheap salesman and does appear to kind of glide over the truth/facts a lot ... but most of his lies are in the exaggeration and "Trust me" category. Taking his company through bankruptcy is not really the same as an individual bankruptcy. Plus, he did the financing of his casino company out in the open and every one I know saw those reorganizations coming years in advance. He simply out-slicked his shareholders, (and his bondholders) few of whom were individuals anyway. No serious investor would ever put money into one of his ventures without having the "T's crossed and the I's dotted." It's not that he fleeced sophisticated investors, but that he fleeced people who thought they were sophisticated investors.
Biden seems to have mellowed and learned from age. That was some dirty crap he pulled in law school, but these days, he seems more given to misspeaking than to bald-faced lying. He manages to come off as someone's goofy uncle. He did take credit for "Killing Bin Laden" and saving General Motors, neither of which was exactly true. It kind of startled me that a man in his position would so boldly brag about what was essentially an execution. It was fine with me that it happened, but they kind of went from "We buried him at sea, following all the customs of Islam" to "Look at us! We got him dead! We did it ... not you guys!" Taking all the credit for a killing is simply untoward and tacky ... and in this case, not exactly true.
Huckabee is simply a weird guy ... the guy in your high school class who carried a bible to school every day. I cannot make sense of a lot of what he says, so I can only conclude that he is one of those guys whose opinions are kind of fluid ...depending on what he read most recently, and depending more on the presentation of a given issue than on the substance. He might lie at times, but since he does not really know that he is lying, it takes the edge off. All in all, I think he believes whatever he says to be true.
Warren's stuff is a bit more duplicitous. It is similar to Obama's claim to be a foreign student in order to get financial aid at Occidental College. Her's was clearly an intended and straight-out lie, with the hopes of really fooling some people ... fooling them down deep, and being awarded something that she had not earned or was not qualified for.
But Hillary takes the cake ... from her financial dealings with Robert L. "Red" Bone to Whitewater, to the day-one "reorganization" of the White House Travel Office, she has never not had some sort of lie working. With her it is constant. She lies even when she does not have to lie. It is in her DNA. She cannot ever tell the truth.
