This Gallup poll on gun ownership and usage contains all of the usual data: more Republicans than Democrats own guns. But there is a fascinating split in the reason people own guns that is given at the end of the results: among people who own guns, Democrats cite personal protection as the reason more than do Republicans, and all three categories, Republican, Independent, and Democrat, poll at 64% or greater for personal protection.
So, while the liberal narrative holds that guns are the cause of crime, and restricting access to guns would decrease crime in the United States, there is a significant minority of Democrats who own guns for personal protection. I think anyone you owns a firearm for personal protection would not be sympathetic to increased gun control laws.
That little factoid in this poll just might be a decisive factor explaining why gun control is increasingly unpopular, while laws bolstering the ability of citizens to protect themselves, like liberalized concealed weapon laws, have been passed in almost 40 states.
Democratic Party leadership is mostly composed of the most liberal members, like my own Senator Diane Feinstein. But even they have stopped pushing for more gun control laws simply because they have been slapped down too hard by the voters, and the reality that not every Democrat is against gun ownership.
