When President Obama won his historic election in 2008, gun sales increased in record numbers. Well, the same trend is heating up in after his reelection Tuesday. According to data released by the FBI, in October, the number of firearms background checks performed on potential gun buyers across the U.S. increased 18.4%. The number of applications for gun ownership is considered an indicator for future gun sales. Experts believe the spike in applications is linked to nervousness that the Obama administration might try to tighten gun control laws. In 2008, after President Obama was first elected, the FBI conducted 12.7 million background checks for that year alone, compared to 11.2 million in 2007, a 13.4% increase.
