** In this Nov. 6, 1968 file photo Shirley Chisholm is surrounded by campaign workers flashing the victory sign, shortly after she won election to Congress from New York City's Bedford-Stuyvesant district, on Nov. 6, 1968. In 1972 Chisholm became the first black woman to pursue the presidency, waging a campaign to end the Vietnam War and give voice to the silent in the nation's policy-making. Jesse Jackson followed in 1984 and 1988, paving the way for the candidacies of Alan Keyes, Al Sharpton and Carol Moseley Braun. (AP Photo, File )
