On “CBS This Morning” Monday, former House speaker Newt Gingrich said he was confident that he would emerge from the New Hampshire presidential primary Tuesday as the clear conservative alternative to former Massachusetts governor Mitt Romney.

“I think I’ll do well enough here Tuesday night that in South Carolina on Wednesday morning, it will be very clear that the game is on between a Reagan conservative and a Massachusetts moderate,” the Republican presidential candidate told Charlie Rose...

...Gingrich went on to compare himself to his intervierwer. “He used millions of dollars of negative and sometimes very false ads in Iowa to stop the momentum, when we had a purely ideas-oriented campaign — almost a Charlie Rose-style campaign,” he said, referring to Romney. “We had to find a way to balance that out.”
