INDEPENDENCE, Iowa — No more Mr. Nice Guy. Newt Gingrich will “draw a very clear contrast” with Romney “every day” immediately after the Iowa caucuses Tuesday, the former House speaker told ABC News. “Everything we say will have Romney’s quote, Romney’s videotape, Romney’s record; it’ll all be based explicitly on Romney,” Gingrich said in an interview in Independence, Iowa. Gingrich has said repeatedly that Republicans should aim their attacks at President Obama, not fellow Republicans. But after getting hammered by millions of dollars in negative ads, Gingrich says he will now return fire, targeting Romney over and over again.
