You would never have seen numbers like this in the mid-1990s. Most people seem to favor restrictions on felons and the mentally ill, but beyond that there’s sharp division. Even on this particular topic:
Just over half of Americans (53%) see a national registry of firearm owners as reasonable, while roughly half say the same of outlawing fully automatic firearms (49%). Fewer Americans favor limiting either clip sizes (41%) or the number of firearms an individual can own (34%).
So we’re not even at a bare majority on outlawing fully automatics these days? I remember when we were pushing 2/3rds of American supporting semi-auto bans (granted, likely out of confusion, but still) in the 1990s. The poll also still show that there’s a significant gap between Republicans and Democrats on this issue, though it’s worth noting you still have about 20% of Dems who aren’t too fond of more gun control.
If these numbers are real, you could very well see a major sea change in this issue once we’re rid of Obama.
