Stymied on Capitol Hill and in state legislatures, supporters of stricter gun control measures are taking their cause to the ballot box.

Voters in four states will decide ballot measures relating to gun control this November. In Maine and Nevada, voters will decide whether to expand background check requirements to include private gun sales.

In Washington, voters will decide whether to take guns out of the hands of people who are subject to extreme risk protection orders, which include restraining orders and people at risk of suicide.

And in California, voters will decide whether to ban the possession of large-capacity magazines. The California measure, Proposition 63, would also require individuals to pass a background check before purchasing ammunition.
