Many of them are still 100% non-transparent, many with entrenched official cultures of vote suppression. This is the result of long standing white bigot wealth and rule, and infestation by Bushwhack Republicans. No question that there are other problems in the South, deep-rooted in slavery. But 'TRADE SECRET' vote counting, when it is so locked in, politically, is a huge blockade to change. Take a look at these charts in the Brennan Center report...
http://www.brennancenter.org/content/resource/is_america_ready_to_vote I don't much care for the Brennan Center. I think they are into protecting voting machine corporation profits, by trying to "mitigate" an inherently fraudulent election theft system. But their charts are interesting as to who is the worst of the worst.
Political pundits almost always fail to discuss who is counting the votes and how, when they analyze political trends in the country. This is gaping omission in political punditry--and I often see it on the left as well.
The voting system is bad all over. The BC identifies California, for instance, as "good" and "excellent" in various categories, but this is within the confines of narrowly defined parameters of transparency: 1% of the votes audited in California. Not good enough. Not nearly good enough. (Some experts that I regard highly say that we need a MINIMUM of 10% auditing--comparison of electronic tallies with actual ballots--to detect most--not all--most fraud and error. Venezuela does a whopping 55% audit, and they have an OPEN SOURCE code--not 'TRADE SECRET' code--system.) California elections are vulnerable to massive fraud; corrupt county election officials are still in place; and the rightwing dragons who own and control the 'TRADE SECRET' code can use it as a meat cleaver (putting Schwarzenegger in office) or a surgeon's scalpel (Prop 8--which I think passed as the result of fraud, and was intended as one of a number of efforts to fracture the center-left coalition that elected Obama, by a big enough turnout to defeat the machines.)
But it is worst in the south. It is nothing short of a repetition of the poll tax and other forms of suppressing the black vote. The entrenched Republican bigot culture
combined with 'TRADE SECRET' vote counting directly results in poor education, black poverty (and in Texas, brown poverty) and a lack of progressive values in government. Count ALL the votes, and I think we will see a dramatic change for the better in the South.
