Standing in the pulpit where the Rev. Martin Luther King Jr. led the historic Montgomery bus boycott, Democratic presidential candidate Hillary Clinton reached out to black voters Tuesday saying the U.S. is still plagued by injustices such as mass incarceration, an epidemic of gun violence and attempts to roll back voting rights. "We must be honest about the larger and deeper inequalities that continue to exist across our country," Clinton told a majority black crowd at the Dexter Avenue King Memorial Baptist Church where King preached his Sunday sermons from 1954 to 1960. Clinton has made frank discussion about the country's lingering racism a central theme of her primary campaign, in an effort to woo the coalition of minority, young, and female voters who twice catapulted Barack Obama into the White House. She's rolled out a series of policies aimed a revamping the criminal justice system, an issue that she and her rivals - Vermont Sen. Bernie Sanders and former Maryland Gov. Martin O'Malley - each pitch as they court black voters who will help choose a nominee.
