I have written a first stab at something that has been missing in the public web, as far as I can tell from bingoogling around, and that is an outline on how to systematically vet a candidate for office.
The piece, available at precinctproject.us and concordproject.org, is written primarily from the point of view of a Precinct Committeeman. But it is general enough to serve as both the jumping off point for activists interviewing candidates and as a set of principles the average well-informed voter can use when deciding among candidates for higher office.
At least, that was the intent.
Most of us have done a very limited amount of vetting candidates, though of course we size them up all the time. But there is a difference between choosing among a group of candidates from their media presentation and actually vetting them. Vetting is a systematic process for discovering the strengths and weaknesses of individual candidates before offering them assistance.
The process of vetting is especially important to Precinct Committemen, who are the ultimate grassroots activists. As members of political parties, committeemen (or precinct captains, delegates, or whatever they are called in your state) are the first line of defense in keeping the bad actors out of politics — and in identifying good public servants, as well.
