Newt Gingrich says the primaries are effectively over.

"I don’t have to go around and point out the inconsistencies of people who are not going to be the nominee. They are not going to be the nominee. . . . I’m going to be the nominee. . . . And the guys who attacked each other in the debates up to now, every single one of them have lost ground by attacking. So they should do what they and their consultants want to do. I will focus on being substantive and I will focus on Barack Obama."
