Speaker Newt Gingrich, taking advantage of a Congressional break to begin selling his new book, said today that he would not rule out a run for the White House in 1996 "if a vacuum developed."

Mr. Gingrich, in interviews at stops across Georgia and on CNN's "Larry King Live," said he would make no final decision until December, the filing deadline for New Hampshire's primary.

"Given the level of publicity and interest that we have, the number of supporters that we have around the country, I don't want to rule it out totally, because you can't tell what's going to happen," he said.
