Colombia presidential runoff shadowed by paramilitaries

Colombia will hold its presidential runoff election on Sunday between Iván Cepeda and Abelardo de la Espriella. Al Jazeera profiles Cepeda, a soft-spoken senator who critics say became a 'hero to the left' after he took on a right-wing president in court. The election is shadowed by the country's paramilitary forces, which have deeply shaped both candidates' lives.
