Yes; if you take a look at the 1964 election results as stored on the Atlas, you'll see that only
33.9% of the voting age population actually voted in Mississippi on that year. Compare this to the overall nationwide turnout of 61.9% and the 1968 Mississippi turnout of 53.3% (from which RBH's second numbers come from).
