South Carolina adopts the secret ballot 1950 (jan 1, 1950 – nov 26, 1979)
Description:
(only able to get the year) This relates to the adoption of a secret ballot as mentioned under number one in the expression of sentiments section of the Omaha Platform. According to Wikipedia, which I don't like to use as a source or frequently use, South Carolina was the last state to adopt a secret ballot.
