Question

boards of elections play which following role in campaigns? assisting partisan campaigns selecting desirable candidates certifying qualified candidates

Explanation:

Election boards are non-partisan administrative bodies focused on ensuring election integrity. They do not assist partisan campaigns (as this would compromise neutrality) or select "desirable" candidates (a subjective, partisan action). Their core role includes verifying that candidates meet legal requirements to run, which is certifying qualified candidates.

Answer:

certifying qualified candidates
