Freshman lawmaker cheers Romney's speech

Romney officially accepted the GOP presidential nomination Thursday evening in Tampa, Fla.

"If there is one takeaway from this week's convention, it is that we have not lost faith in America's greatness or each other, but we need a commander in chief who is going to make sure that better days are ahead of us,” Gardner said. “I believe in America, and that is why I also believe in America's comeback team.”
