(a) The board of elections in each election district shall select and fix as many polling places for each polling district under its jurisdiction, herein or hereafter established as it may deem necessary. For the Island of St. Thomas and St. Croix, the polling places for any polling district may be located outside such polling district if convenience of the voter will be promoted thereby.
(b) In order to facilitate the widest possible voter participation, and to minimize confusion as to the location of polling places, the board of elections of each election district shall provide for the utilization of the same polling places in use in 1968 in the respective polling districts for both the primary and general elections of 1970, so that all qualified electors who voted in 1968 may be able to vote at the same polling places in the 1970 primary and general elections.
