Gallup poll shows MAJOR shifts
1990 vs 2009:
Gun laws should be stricter: in 1990, 78%, fell to 44% today.
Gun laws should stay the same: 17%, now 43%.
Gun laws should be relaxed: 2%, rising to 12% today.
Now, some of the shift could theoretically come from enactment of background checks, etc., during the 1990s, which made the 1990 population segment satisfied. But it doesn't look like that. When asked about handgun bans, 60% approved in 1990, but only 28% in 2009, a drop of 32 points. That matches the 34 point drop in gun laws should be more strict, and suggests that a lot of Americans who supported gun restriction as a concept in 1990 stopped supporting it by 2009.
