Bernard Whitman, author of "52 Reasons To Vote For Obama", argues that Republicans are attempting to disenfranchise African American voters by forcing them to jump through hoops when voter fraud is not an issue. People don't impersonate other people at the polls, for example there has been zero documentation of voter fraud in the history of Pennsylvania. The problem of voter fraud doesn't exist and other voting irregularities are mistaken for voter fraud.
