SELMA, AL - NOVEMBER 01: College students on the NAACP's 'Vote Hard' bus tour canvas encouraging people to vote in the George Washington Carver Homes housing project next to the historic Brown Chapel AME Church November 1, 2008 in Selma, Alabama. The students are crisscrossing Alabama by bus while canvassing neighborhoods to encourage African-American communities to vote. Dr. Martin Luther King Jr. preached in the historic church which was a starting point for the Selma to Montgomery marches in 1965. The marches eventually led to the Voting Rights Act of 1965 ending voter disfranchisement against African-Americans. Americans are gearing up for the first presidential election featuring an African-American to be officially nominated as a candidate for U.S. president by a major party, Democratic contender Sen. Barack Obama (D-IL), who is running against Republican Sen. John McCain (R-AZ).
