Michigan Gov. Rick Snyder is a Republican. Mayor Bill de Blasio is a Democrat. Both men find themselves at the center of crises, which collectively involve thousands of children likely brain-damaged from exposure to lead. **SNIP** On Nov. 7, 2017, de Blasio was re-elected to a second term. Two weeks later, he admitted he knew one year earlier that NYCHA was falsifying documents regarding lead-based paint inspections. Sanders could have called for de Blasio’s resignation, as he did with Snyder. Instead, he personally swore in de Blasio for his second term on Jan. 1, 2018.
