A South Florida law professor, running to unseat Congresswoman Debbie Wasserman Schultz, is calling for a federal investigation into the destruction of all ballots cast in the August 2016 Democratic primary in Broward County. The challenger, Tim Canova, has made repeated public-records requests and filed a lawsuit seeking access to paper ballots cast in his unsuccessful race last year against the former Democratic National Committee chair in Florida's 23rd congressional district. A statistical analysis of the primary conducted last year suggested the election results were potentially implausible." the Broward supervisor of elections, Brenda Snipes, has taken no action on requests ... to examine the ballots. Instead, Dr. Snipes has urged a judge to throw Canova's lawsuit out. Despite the pending records requests and the ongoing litigation, Snipes ordered the ballots and other election documents destroyed. The lack of a paper trail verifying voter choices undercuts the ability to identify systemic election fraud and might make such fraud impossible to detect. The Aug. 30 Democratic primary in Broward was being closely watched across the country. A month earlier ... Wasserman Schultz was ousted as chairwoman of the DNC. She was removed over allegations that she and other party officials had rigged the Democratic presidential primary process to favor Hillary Clinton over Bernie Sanders. The pro-Clinton fix was first divulged in DNC emails ... released to the public in the months leading up to the election.
