I am not certain why this should be a left-right issue, but I find I am almost reflexively on the side of conservatives when it comes to lying about autobiography. They consider it a big deal, and indicative of general character. People of the left don't seem to regard it as important. Less important, anyway.
It might not be as important as I treat it. Hierarchies of sin are tough to assign. But when Hillary Clinton claimed she was named after Sir Edmund Hillary, he of the Everest climb (she was five when it happened), she forever had a great deal to overcome for me to trust her. She's had other such statements, such as trying to enlist in the army. I felt similarly about John Kerry's claims of being in Cambodia and getting a special hat from a CIA guy, or Al Gore's claim that the tie-on-the-doorknob sign from Love Story was about him and Tipper. Obama claiming his mother died of cancer because of her insurance company, and all that mess about basketball and the girlfriends. Bill Clinton, let's not even get started.
They are small things, perhaps. They are fibs, about events which have little effect on us one way or the other. They are just blowhard comments
One major reason may be that I did it for a year myself, when I was 18. Just as I graduated from high school my parents moved to another state, I took a live-in job at a summer resort, and I entered college hundreds of miles away in the fall. I reinvented myself, including my past, because there was no one to say me nay. I sometimes wonder if any of the stories I told about myself that year were true. Most were based on a true story, as they say, exaggerations and partial truths. A few were like Hillary's naming story - they just sounded like cool things that weren't impossible and would be great to have be true. I don't recall an abrupt stop to this behavior, but I can only think of examples from that year. I did continue to repeat some.
So I don't get it when the truth comes out and the person doesn't just slink away out of the public eye forever. When it becomes known that you didn't go to Cambodia and can't possibly have a magic hat, how do you face people? Conservatives seem to lie about the standard stuff - affairs, corruption, money - and when they get caught, get told by others to slink away, and they usually do. Or sometimes, they try to spin it down without denying it. But they generally have what would be my reaction - humiliation and an attempt to exit gracefully, with apologies. Especially as an adult.
But I don't recall in recent history people of the right getting caught in one of those blowhard things, claiming to have been cum laude when they didn't graduate or being drafted by the Packers when they weren't even starters in college. Different style perhaps. More likely to exaggerate what opponents did, maybe. I'm sure there must be something - Newt Gingrich seems likely, but I can't think of anything. If it is true that a lot of conservatives are like me on this score, they likely removed them from the pool. I can't understand when liberals don't have the same response.
