The poll finds broad agreement on two specific proposals discussed since the Parkland shooting. An 85 percent majority of Americans supports a law allowing police to take guns from people who have been found by a judge to be a danger to themselves or others, which are known as red-flag laws and exist in five states, including California and Connecticut. A 72 percent majority supports raising the legal age to buy rifles and shotguns to 21 in all states.

Red-flag laws have the support of more than 8 in 10 Democrats, Republicans and independents, including at least two-thirds who support them “strongly.” Raising the legal age for buying rifles and shotguns garners support from 87 percent of Democrats, 70 percent of independents and 55 percent of Republicans.

Most Americans living in gun-owning households also back proposals for a red-flag law and increased age limits. More than 8 in 10 (81 percent) of those in gun-owning households support red-flag laws, and 63 percent support raising the national age to buy rifles or shotguns to 21 years old. Support for both policies is even higher in households without guns.
