Which candidate selection method is the most democratic?

This article suggests guidelines for identifying the ramifications of central elements of candidate selection methods for various democratic dimensions - participation, competition, representation and responsiveness - and analyses their possible role in supplying checks and balances. It proposes employing a three-stage candidate selection method: in the first stage a small committee appoints candidates to a shortlist; in the second stage a selected party agency may add or remove candidates using a special procedure (absolute majority vote, for example) and also ratify the re-adoption of incumbent candidates; and, finally, party members select candidates for safe seats or safe list positions among the proposed candidates. The article also recommends employing moderate requirements for candidacy; the use of a non-majoritarian voting method; and allowing the national centre a say in candidate selection.
