President Clinton is sworn in for his second term by Supreme Court Chief Justice William Rehnquist during the 53rd Presidential Inauguration Monday, Jan. 20, 1997. His daughter Chelsea is at his side. House Speaker Newt Gingrich of Georgia and his wife Marianne are in the background. Dredging up a past that Newt Gingrich has worked hard to bury, the GOP presidential candidate's ex-wife says Gingrich asked for an "open marriage" in which he could have both a wife and a mistress. In an interview with ABC News' "Nightline" scheduled to air Thursday, Jan. 19, 2012, Marianne Gingrich said she refused to go along with the proposal that she share her husband with Callista Bisek, who would later become his third wife.

Question: Does this revelation spell the end to Newt Gingrich's bid for the presidency?
