Newt and Callista Gingrich shared the stage at the Republican National Convention Thursday, taking turns as they spoke about the economy, energy independence, and Ronald Reagan. “It's striking how President Carter and President Obama both took our nation down a path that in four years weakened America's confidence in itself and our hope for a better future,” Newt said, and compared Mitt Romney to Reagan. “The Romney plan for a stronger middle class has deep roots in Reagan's approach,” he said. Callista urged voters to support Romney come November.
