Excerpts from a new book by Arkansas Supreme Court Justice Tom Glaze.  A snippet shows the role of official collusion in vote buying schemes in the Southeast:

Taylor, who had served a couple of terms as the county treasurer in the late 1950s, and Eaton gave similar accounts. They told not only about vote buying but all sorts of illegal acts. Although the voting age was then 21, Eaton said he started voting when he was 16 and that later, when he became an election judge, he and the other officials allowed anyone who showed up to vote whether they were of age, had a poll tax or, later, had even registered to vote. All the ballots were tossed into the ballot box and counted. It didn’t matter. No one ever double-checked the registration affidavits to see if the people who signed at the polls matched the number of votes cast. No one, Democrat or Republican, ever blew the whistle on the other side.
