Remember the Parkland, Florida high school shootings?  On Valentine’s Day, February 14, 2018, 17 students and staff members at Marjory Stoneman Douglas High were killed by a 19 year old former student Nikolas Cruz armed with an AR-15 style semi-automatic rifle and multiple magazines.  “The Parkland effect” – led by survivors of the shooting -- helped change gun laws in Florida, but Steve LeVine of Axios.com wonders if Parkland will affect the November elections.
