A month after she saw the editorial, Schwartz founded a political committee to get the assault-weapons ban on the 2020 ballot. The committee—called Ban Assault Weapons Now, or BAWN—aims to ban the future sale of semiautomatic assault rifles throughout Florida. With guidance from Parkland’s Democratic Representative Ted Deutch, Schwartz has gathered a team of professional political strategists and Floridians directly affected by gun violence, including both the Parkland and Pulse shootings. The group also has a rare advantage—bipartisan support. BAWN has partnered with the prominent Republican donor Al Hoffman and his gun-control-advocacy organization, Americans for Gun Safety Now!, which is made up almost entirely of Republicans who support an assault-weapons ban. They have now formed a coalition, Do Something Florida! Under their division of labor, BAWN will handle the gathering of petition signatures needed to get on the ballot, and Americans for Gun Safety Now! will direct an education and advocacy campaign arguing the need for an assault-weapons ban.

On Monday, representatives from the coalition will meet for a ceremony in front of the Broward County Supervisor of Elections Office to honor the 17 students and staff members killed a year ago in the Parkland shootings. They will then submit their first round of ballot petitions for verification.

Do Something Florida! faces a difficult task. BAWN has approximately a year to collect 766,200 verified petition signatures, and then will need at least 60 percent of the vote in favor of the ban in a historically gun-friendly state. On top of that, it’s sure to face organized opposition from gun-rights activists.

Ballot initiatives have already been used by other states for gun-control measures, some more successfully than others. In 2016, Maine voted against an initiative for mandated background checks on all gun sales, and Nevada narrowly passed a similar measure before the state’s attorney general struck it down. This past election cycle, Washington State voted in favor of an initiative implementing multiple gun regulations, and organizers in Oregon also intend to have a question on the 2020 ballot that would ban assault weapons. Seven other states and Washington, D.C., have already banned the transfer or possession of some assault weapons through legislation.
