Do the Dems Have a History of Rigged Elections?!?

Barack Obama (D-IL) addresses the crowd during his acceptance of the Democratic presidential nomination at Invesco Field at Mile High at the 2008 Democratic National Convention, August 28, 2008 in Denver, Colorado. Obama's acceptance speech coincides today with the 45th anniversary of Rev. Martin Luther King Jr. delivery of the "I Have a Dream" speech. Sen. Obama is now the first African-American to be officially nominated as a candidate for U.S. president by a major party. (CQ Roll Call via AP Images)
