Venezuela opposition leader's security chief arrested days before election 

caracas, venezuela — The security chief of Venezuelan opposition leader Maria Corina Machado was arrested early Wednesday, her Vente Venezuela political movement said.  The arrest came less than two weeks before the July 28 vote, where the opposition coalition's candidate, Edmundo Gonzalez, is polling significantly ahead of President Nicolas Maduro, who is seeking a third term.  Machado, who resoundingly won the opposition's October primary, was barred by a court from running in the election over alleged fraud, which she denies.
