Why: I have a serious medical condition which limits how much I can take on. I spent a lot of years as a military wife and devoted mother, raising two special needs sons. This was just a helluva lot of work, more than most people seem to appreciate. Trying to stay up on The Issues was just not something I could manage. My plate was overly full as is. I saw no reason to vote if my choices were not based on some kind of meaningful information or opinion.
From what I gather, you see higher rates of voting and political activity in older people, precisely because their plate is less full (with launching a career, finding romance, raising kids, etc). It is possible that as I get older and my life works better, I may someday feel able to effectively participate in the process. I haven't made any decisions one way or the other. It wasn't a Stance. It was happenstance.
