Right, you generally have to be involved to some degree in political matters even if only as a community or interest-group activist to make it to a viable candidacy. Kelly is not only married to Giffords but has been the other visible face of her gun-issues PAC.
This is a critical element of the lack of a down-ticket “bench” at the town/county/small state level. A majority of such elected positions are made by design to be so the office holder needs to “have a life” otherwise, but at the same time require attention “in your own time” when the council or committee or chamber are not in session. It’s not just campaign financing that costs you.
