IMO Yahoo Business posting promotes a big lie about gun sales and Obama by running Business Insider

article on smith & Wesson. The article is more of an opinion piece quoting Smith and Wesson claims gun sales went up after Obama was elected.. The opinion piece states
"The explanation for this phenomenon is pretty simple: If there's a risk that you won't be able to buy guns in the near future, then buy your guns now."

I rather believe it was fear of a black president that caused the huge uptick in sales.
