Newt Gingrich took aim at President Obama's policies today during a town hall meeting in Oklahoma, where the former House speaker hopes to do well on Super Tuesday.

"You can't put a gun rack in a Volt," Gingrich told the crowd at Oral Roberts University, according to the Tulsa World.

Gingrich has lost ground in national polls as Rick Santorum has been surging in recent weeks. He has not campaigned much in Michigan, which holds a primary on Feb. 28, and has instead been raising money and campaigning in the West.

Oklahoma is one of several states that will hold GOP primaries or caucuses on March 6, which is Super Tuesday.

The Tulsa newspaper said Gingrich also charged Obama again with waging a war on religion, something the former House speaker has said repeatedly since a controversy erupted over an Obama administration policy requiring religious-affiliated employers to provide free birth control.
