Did you even watch the video for the link you sent? In it it said that there was no malice, that all of the odd votes could be linked to simple clerical errors.
I'm not going to keep arguing beyond this post, but it would be really simple for you to Google "How exactly does requiring ID "suppress" someones right to vote?" instead of asking me. I did, and there are plenty of articles to read if you really want to enlighten yourself on how racist tactics are used to keep minorities from voting.
Voter ID is one of many different prongs of an organized attack on voting and voters rights, such as requiring proof of citizenship, tightening up voter registration drives, shortening early voting periods, repealing same-day voter registration and purging voter rolls during a prohibited time before an election, in addition to requiring photo IDs. Along with tactics like putting these false flyers on cars before an election:

So it isn't just the Voter ID, the Voter ID laws are systemic of a much larger problem that the right uses any tactic it can use to keep minorities from voting. Except the one tactic that would work, which is caring about the needs of the under privileged in this country.
