Still, roughly 4 in 10 likely voters say gun laws in their individual states should be made more strict, new Quinnipiac University/New York Times/CBS News polls find. But as many voters in Virginia say the laws should stay the way they are, as do about half of voters in Colorado and Wisconsin. (Most interviews in Wisconsin were conducted before Sunday’s shooting at a Sikh temple in Oak Creek, Wis.) The polls found that 6 percent in Wisconsin, 8 percent in Colorado and 9 percent in Virginia want their gun laws made less strict.

Many voters seem to lack confidence in the effectiveness of more stringent laws. About 6 in 10 voters in Virginia and Wisconsin and two-thirds in Colorado say stricter laws would not deter gunmen intent on mass shootings.

“I honestly believe that criminals can get guns no matter where or when or how,” Phyllis Everitt, 65, of Aurora, Colo., said in a follow-up interview. “I realize this man purchased them legally, but if he hadn’t and he was determined to do this, he probably would have gotten them illegally,” she said, referring to James Holmes, who has been charged with killing 12 people and wounding 58 in an Aurora movie theater last month.
