Newt Gingrich insists that he is not going to New Hampshire this weekend because he's planning to run for president . And that's just the way New Hampshire wants it. A poll of 400 Republicans registered in the state, released today, found that 52 percent would encourage Gingrich toforget about running for presidentif they could speak to him during his visit. (Only 18 percent liked the idea.) If Gingrich were in the race right now, he would place fourth at only 5 percent -- far behindBob Dole, and trailingPat BuchananandSen. Phil Gramm. Meanwhile, a new NBC-Wall Street Journal poll suggests thatPresident Clintonwould wallop Gingrich in a national face-off, 55 percent to 28 percent.
