Mo. R. Gov. Bar Jud. 10.31
The conduct of candidates for any judicial office to be filled pursuant to article V, sections 25(a)-(g) of the Missouri Constitution shall be governed by and be in accordance with the applicable provisions of the Rules of Professional Conduct and the Canons of Judicial Ethics. In particular, the aspiration of lawyers for judicial position should be governed by an impartial estimate of their ability to add honor to the office and not by a desire for the distinction the position may bring to themselves. If a judge, or a person in an office of a judicial nature, becomes a candidate, he or she should refrain from all conduct that might tend to arouse reasonable suspicion that he or she is using the power or prestige of his or her judicial position to promote his or her candidacy. He or she should not permit others to do anything in behalf of his or her candidacy that would reasonably lead to such suspicion.
It is the duty of The Missouri Bar to endeavor to prevent partisan considerations, political or otherwise, from outweighing judicial fitness in the selection of judges. The Missouri Bar should protest earnestly and actively against the selection of those who are unsuitable for the bench.
