http://www.usccr.gov/pubs/pubsndx.htmVoters were turned away because they were on a list of disqualified voters (because voter rolls were purged of mainly black people based on felonies that they had never committed) and because the polls were closed early or moved without notice.
There's a section with anecdotal infromation such as what you mentioned, as well as a findings section that concluded, among other things, that African American voters were nearly 10 times more likely to be disenfranchised than white voters.
Also it talks about the fact that machines were set up to 'kick out' invalid ballots in wealthier counties so that the voter could re-vote; while in poorer counties it simply didn't count the vote but did not alert the voter. Consequently, "
in Gadsden County, the only county in the state with an African American majority, approximately one in eight voters was disenfranchised. In Leon County, on the other hand, which is home to the prosperous state capital and two state universities, fewer than two votes in 1,000 were not counted. In Florida, of the 100 precincts with the highest numbers of disqualified ballots, 83 of them are majority-black precincts."
A more entertaining place to read about this might be at the
