The first election I remember was Reagan/Mondale in 1980. Honestly, Ronny charmed the pants off of the nation. I barely remember Jimmy Carter as president, because he was just so "Meh," and "Blah" there wasn't that memorable, but I was 8, and that's when I was first aware of American Politics. As far as the media represents how it works.
He also got me into all the Space Stuff. I missed Apollo, but not Skylab, the Space Shuttles (Including the one I already mentioned) my mom, and dad had an extensive library of Science Fiction. I mean, we didn't have a Living Room, we had a Library, and a den in the basement with the TV/VCR. You had to walk past the books, and downstairs to get to the TV for after school cartoons.
So anyway, that shaped my childhood. I started with Tolkien as bedtime stories, and this was right after Star Wars, but I was still stuck on Indiana Jones, and (Dino deLaurentis') Dune. That's when I started reading Azimov, Anthony, and Heinlein, among others.
Also when I learned about Drugs. I mean, my parents were "Hippies," and hated being called hippies. They would correct people and say "Baltimore Street Freaks," but they smoked, and I got contact buzzes before I got to take DARE classes, and heard "Just Say No to Drugs."
So, in many ways, my entire childhood was shaped by Reagan. He's still the first face, voice, and hairdo that pops into my head when you say "President of the United States," not to mention kicking off the Bush dynasties, the geo-political situations that led to the Heirloom War, Terror war, and most of my fictitious "Atrocity Wars." That was my first timeline, and first setting, when I started writing Science Fiction.
So, I'll just have to call that a lifechanging event. I probably would have been a writer either way, but I have to give credit to the Gipper for a lot of What I write.
