Democratic share of Mississippi white vote, post-1964

I think the white vote for Carter in Mississippi decreased more than four points from 1976 to 1980. If you check black counties like Sunflower, Coahoma and Tunica, you will see that not only the turnout increased from 1976 to 1980 but also that the % for Carter increased too (Ford had more black votes than Reagan). This is an evidence that there was more black turnout in 1980 than in 1976 and larger % of the black vote for Carter in 1980 than in 1976.
So, the decrease of the White vote was more significant.

It is important to observe that Jimmy Carter performed better in Hinds County in 1980 than he did in 1976. In 1976, Ford won by a 23 point margin. In 1980, Reagan won by a 10 point margin. Hinds was more white in that time, but maybe, the black population there reduced the Republican margin.

In rural white counties in the Southeast of the state, there was a large swing for Reagan.
