Answer:
The plan of Missouri originated from the non-partisan parts of the merit plan, together with other variations. Back in 1940, Missouri has acquired many states that used similar methods under their policy.
Thus under a plan, the non-partisan usually reviewed the candidates selected from judicial positions. After reviewing the commission's drafts, a selected list was sent to the governor of the most qualified. The governor takes 60 days to pick the best candidate from the given list. If the governor fails to select after 60 days elapses, then the commission makes a selection.
