The pollster, columnist and marketing strategist John Zogby was one of the first to see the mass murder at the high school in Parkland, Florida as a “tipping point” in America’s debate over gun control.  The children, he predicted, the students will lead a national movement towards more regulation of firearms. What were the first signs that led him to that conclusion?  And does he think the killings at Marjory Stoneman Douglas High will play a role in the 2018 elections?  And what about the backlash of smears and conspiracies rampant on the internet?  Will the trolls drown out the students?
