President Nicolas Maduro is widely blamed for Venezuela’s unprecedented economic crisis, but on Tuesday he vowed to make “great changes” if re-elected this weekend. The 55-year-old gave no specifics about how he would turn around Venezuela’s economy. The OPEC nation is in the fifth year of a grueling recession. Maduro’s pledges ring hollow to many Venezuelans who blame him for hyperinflation, food shortages, the return of once-controlled diseases and mass emigration. Meanwhile, Maduro blames a U.S.-led “economic war," including recent sanctions from the Trump administration, for the hardships.
