No he couldnt have. They had a veto proof majority salivating to ban classes of weapons again.Much worse legislative prospect?
He was the president and could have vetoed that prospect.
Dont forget the republicans only like guns when its a voting issue. Otherwise all the establishment right wants us disarmed too.
Think about it. Handguns kill more people than any other gun yet they want AR's and AK's and other semi auto rifles. Why? I think its because they want to do something we would shoot them for. An AR is a much better defense and offense weapon against a large group. If they thought what they said they did they would be going after handguns.
Doesnt change the fact the bump stock ban took the wind out of thier sails and is easier to fight then a law put forth by congress with a veto proof majority. And the veto proof would be a talking point in court too
