This is a pretty vague poll, after all, it doesn't ask specific questions about what new firearm laws the public might support.
For example, I support moderate regulation of firearms, but I don't believe in any new laws...just the ones we already have. I guess I'm in the "almost 7 in 10", although, I definitely would not support a new AWB or limits on magazines.
Someone pointed out the lack of understanding about gun laws, which is a serious issue for this type of poll.
For example, I was talking to a group of people at work the other day. They believed that long guns needed no background check to purchase!
