Brazilian presidential candidate Eduardo Campos died in an airplane crash in the city of Santos Wednesday, television network GloboNews reported. A source in the Brazilian Socialist Party had previously said that Campos was on the Cessna 560XL that crashed. Campos is a former governor of Pernambuco state who had the support of roughly 10 percent of voters in recent polls. He positioned himself as a business-friendly leftist and was a former ally of President Dilma Rousseff, who is seeking a second term.
