Frank, the allegations that some African-Americans were not allowed -for a variety of reasons- to vote in South Florida is under investigation. While I am sure that racism may have played a part, there are many legitimate reasons why they were disinfranchised.
For one thing, if you move and don't notify the Supervisor of Elections, you will not be on the rolls in the new precinct. In some counties, if you don't vote for two years, you are purged from the rolls. Illegal aliens are not allowed to vote; there are a lot of those in South Florida.
You must bring a picture ID as well as your voter registration card. Many did not.
There were apparently a lot of problems in South Florida. Hopefully we'll get them sorted out and, if illegal acts ocurred, the responsible parties will be held accountable.
To intimate, as you have done, that it was all racism serves no useful purpose and is divisive in the extreme.
To a child with a hammer, everything is a nail.
