A majority of Americans opposes a ban on semi-automatic weapons – the guns more commonly known as assault rifles – according to new numbers from Gallup.

Fifty-seven percent of Americans oppose a ban on the guns, compared to 40 percent who favor a ban. Support has dropped 8 percentage points from a year ago, when favorability ticked up in wake of a mass shooting in Las Vegas.

But while nearly 6 in 10 Americans say they are against an assault rifle ban, almost the same number are in favor of stricter gun laws. Gallup on Wednesday released poll results that showed 61 percent of Americans support narrower gun restrictions.

Both findings come after nearly a year of feverish gun-control activism in the wake of a school shooting in Parkland, Florida. Gun control also remains a prominent platform issue for many Democrats as the 2018 midterm elections.

Results from both surveys split sharply along party lines. Democrats are more than twice as supportive of an assault rifle ban than Republicans, with 56 percent of Democrats for a ban and just 25 percent of Republicans in agreement. Similarly, nearly 9 in 10 Democrats are in favor of stricter gun laws as opposed to just 31 percent of Republicans.

Support for stricter gun control measures typically spikes after a mass shooting event and falls again once the event fades from the public conscience.
