I think this latest boom in gun sales is different than the earlier ones that were driven primarily by Democrat gun control fears. I think this one has a much more pronounced aspect of people feeling the need for self defense, not just in the home but wherever they are. I bet this round of sales will have a much higher proportion of new buyers getting concealed carry permits than in the past.
The increase in violent crimes such as home invasions fueled many firearm sales.
The Democrats just hate it that people are buying guns and applying for concealed carry permits, while it is the same Democrats who made people less safe by inviting in Mexican drug gangsters and mid-East terrorists.
