Curtis Sliwa

Republican Age: 66

The Guardian Angels, which Sliwa founded, were the self-appointed garrisons of public safety when the city was experiencing a crime wave in the 1970s and 1980s. (Sliwa himself was kidnapped and shot in the early 1990s.) In March, Sliwa took a hiatus from his populist radio show to run for mayor on the Republican ticket and quickly garnered an endorsement from the Staten Island GOP. While he has focused his campaign on crime, in his announcement he said his bid was an attempt to “resurrect us from the eight years of Bill de Blasio.”
