I have, while working in the Soviet Union, participated in an election. I, too, had a right to vote, as I was a working member of the community, and nationality and citizenship is no bar to electoral rights. The procedure was extremely simple. A general meeting of all the workers in our organization was called by the trade union committee, candidates were discussed, and a vote was taken by show of hands. Anybody present had the right to propose a candidate, and the one who was elected was not personally a member of the Party. In considering the claims of the candidates their past activities were discussed, they themselves had to answer questions as to their qualifications, anybody could express an opinion, for or against them, and the basis of all the discussion was: What justification had the candidates to represent their comrades on the local Soviet?
  As far as the elections in the villages were concerned, these took place at open village meetings, all peasants of voting age, other than those who employed labour, having the right to vote and to stand for election. As in the towns, any organization or individual could put forward candidates, anyone could ask the candidate questions, and anybody could support or oppose the candidature. It is usual for the Communist Party to put forward a candidate, trade unions and other organizations can also do so, and there is nothing to prevent the Party’s candidate from not being elected, if he has not sufficient prestige among the voters.
