This Washington Post story about the surprising outcome in South Carolina’s Democratic primary for U.S. Senate on June 8 suggests that the result may have been affected by the order of candidates on the ballot. Apparently in South Carolina primaries, the candidates are listed in alphabetical order.
The story also suggests that Republicans may have raided the Democratic primary and voted for the Democratic candidate who was perceived to be the weaker of the two. That idea will probably be helpful to the new Republican Party lawsuit to obtain a closed primary for itself in South Carolina.
