Good post, Marokai.
I don't disagree with most of what you wrote. Everything that parties do concerning election law is designed to better their chances of winning. I think that's pretty clear. Republicans are also undoubtedly better at the game.
I'm only disputing the supposedly racist nature of the proposed legislation. In fact. I think it's rather racist to assume that Blacks are too dumb to pay attention. Level of being informed, IMO, is much more a matter of class and education level than being a racial or ethnic minority.
Part of it might go into education levels and income, quite simply those who are better educated tend to have more time to vote. Many people, especially those who tend to be poorer likely don't know the take time off to work laws for example.
Anyway it might be more ideological based that also winds up being racially based, but fact of the matter is blacks in Florida tend to make up a much higher proportion of the early vote than the Election Day vote.
Now perhaps its targeted at Democrats in General, and its just a coincidence that blacks are impacted, but with that being said, it doesn't take a genius to figure out that if whites in the Panhandle were the highest turnout group during Early Voting instead of blacks, this legislation wouldn't exist.
