The National Rifle Association plans to spend $40 million this election year, with $15 million dedicated to depicting Barack Obama as “bitter” toward guns and as a challenger to the Second Amendment, Politico.com reports.

Keying off a spring fundraising speech in San Francisco in which Obama said that small-town Americans turn to guns and religion to cope with their anger about the economy and Washington, D.C., Chris Cox, head of the NRA's political arm, told the Web site, “We look forward to showing him 'bitter.'"

Cox said his organization's 4 million members understand that if Obama is president, he may support anti-gun Supreme Court nominees and reinstate the Washington, D.C., handgun ban, Politico reports. The ads will alternate between reaching NRA members and tens of millions more firearms owners nationwide. The gun rights group will most likely target its ads to some of the 15 battleground states, the Web site noted.

An Obama campaign spokesman responded to news of the expected ad buy by telling Politico that the presumptive Democratic presidential nominee "has always believed that the Second Amendment protects the right of individuals to bear arms," and at the same time wants to "enact common-sense laws, like closing the gun show loophole and improving our background check system, so that guns do not fall into the hands of terrorists or criminals.”
