Poll results regarding support for gun control are changing

I wonder how much of this change is do to the change in the questions used in these polls. I believe that the older polls didn't include an option for making gun laws less strict.

WASHINGTON, Oct. 11 (UPI) -- A new Gallup poll says the gap is closing between people in the United States who support stricter gun laws and those opposed to new laws.

A survey last week found that 51 percent support stricter laws governing the sale of firearms. Those who said the laws should either be kept as they are or made less strict was 47 percent. Between 1990 and 2000, 60 percent of Americans favored stricter laws, Gallup said Thursday in a release.

The poll found that a majority of residents in the East and West favor stricter laws, while about half of those in the Midwest and South are opposed. Two-thirds of Democrats favor stricter gun laws, while a majority of Republicans and independents would rather laws remain as they are or become less strict.

The survey result, based on telephone interviews with 1,010 adults, has a margin of sampling error of plus or minus 3 percent. . . . .
