A Gallup poll released on Wednesday found people are more likely to oppose a ban on assault weapons now than at any time over the past two decades, in the wake of a growing number of terrorist attacks and mass shootings over the last few years.

A little over one-in-three people would support a law making it illegal to manufacture, sell or possess semi-automatic guns known as assault rifles, according to a Gallup poll conducted Oct. 5-9. Support for banning this type of firearm peaked in 2000 at nearly 60 percent, a few years after former Democratic President Bill Clinton signed a federal assault weapons ban in 1994.
