1.)Is it your obligation to run for office at some point and time in your life? No absolutely not. I do believe one has a civic duty to their fellow citizens to a certain extent, but running for office is not the only way to fulfill that duty.
2.)If you have never ran for office, why haven't you done so?, do you feel that you have neglected your civic duties because you haven't done so? Skeletons, skeletons, skeletons....
Seriously, though, I think my talents are better utilized elsewhere. Further, I don't have the ability to fake smile when I don't mean it & all-too-often I find my foot in my mouth. Such qualities do not make for an electable politician.
I certainly do not feel I have neglected my civic duties, however. Hosting the home to a community of highly intelligent, civic minded debaters is my way of giving back to my fellow citizens (and if you've been to the chats recently, you likely know all about how we're expanding this as well). I don't have much faith in modern government's ability to govern efficiently and effectively and I don't think I can change that by running for office. I won't work for any bankrupt systems, public or private. I'd rather work against them, to enact change from the outside rather than inside.
3.)If you have run for office in the past, has it helped you appreciate your civic obligations and government in general? N/A
Good luck on your run, Nebraska!
