Umm. Can't you sound out the words?
Households that don't own a gun = 69%
I know that you can't remember things for very long. Actually your memory is very very short term. So, I'll help you out with your handicap.
There have been a lot of mass shootings lately. Public sentiment is shifting away from supporting practically unregulated gun ownership. That 69% of non-gun owning households is called a super majority. The poll you cited was 2017. Remember when I said public sentiment is shifting away from supporting practically unregulated gun ownership? Maybe you forgot but this is the year 2018 and since that poll was taken in 2017, we've had a lot of mass shootings and public sentiment is shifting.
I know you can't remember things for very long, so I expect I'll just repeat this all to you very soon.
