Former President Jimmy Carter says it's "highly unlikely" that he would have been elected as president had it not been for Martin Luther King Jr. (The Washington Post)

Former president Jimmy Carter told a crowd gathered on the National Mall to commemorate the 50th anniversary of the March on Washington that Martin Luther King Jr. would be disappointed to see present day voter I.D. laws and the Supreme Court's recent decision to strike down a key part of the Voting Rights Act.

"I believe we all know how Dr. King would have reacted to the new I.D. requirements to exclude certain voters, especially African Americans," Carter said. "I think we all know how Dr. King would have reacted to the Supreme Court striking down a crucial part of the Voting Rights Act just recently passed overwhelmingly by Congress."

Carter used the same line of argument to decry the high unemployment rate among African Americans, and so-called "stand your ground" laws, among other things.

"There’s a tremendous agenda ahead of us, and I’m thankful to Martin Luther King Jr. that his dream is still alive,” Carter said in conclusion.
