(AP) — With polls showing him running well in Iowa and New Hampshire, presidential hopeful Bernie Sanders took aim at what might be unusual territory for a self-described democratic socialist: the Deep South. Yet a crowd of more than 5,000 packed into Boutwell Auditorium in downtown Birmingham, Alabama, Monday night to hear the Vermont senator, while nearly 1,000 milled outside in freezing temperatures. Sanders said his message of raising the minimum wage, free college tuition and paid family medical leave cuts across regional lines but acknowledged that the work to get that message across was harder in a state like Alabama. Sanders must make up ground with black voters in Southern states to remain competitive with front-runner Hillary Clinton. Before his speech, Sanders visited some of the city's poignant and painful sites in the fight for civil rights.
