The survey, conducted Feb. 22-26 among a national sample of 1,992 registered voters, found 50 percent of those polled support equipping teachers and school staff with concealed firearms to respond in the event of a school shooting. Forty-two percent of voters said they do not support such a policy, which Trump has embraced following the Feb. 14 high school shooting in Parkland, Fla.

The poll also found support for stricter gun control laws has risen 4 percentage points, to 68 percent, since a Morning Consult/Politico poll conducted Feb. 20, while the share of those opposing stricter laws dropped 5 points to 25 percent. Republican support for stricter gun laws is now at 53 percent, up 8 points from last week’s poll. The most recent survey has a margin of error of plus or minus 2 percentage points.

Along with arming some teachers, Trump, who said Monday he met with National Rifle Association leaders over the weekend, has voiced support for gun control measures such as strengthening background checks, raising the purchasing age from 18 to 21 for certain firearms and banning bump stocks.
