Richard Nixon—disgraced former president, political scoundrel ... and tender romantic? Six love letters from Nixon to his wife will go on display this week at the Richard Nixon Presidential Library to celebrate what would have been Pat Nixon's 100th birthday, reports AP. The letters were written by the former president from 1938 to just before his marriage to Pat in 1940, and show a little-known tender side: In them, Richard uses his nicknames for Pat, such as "my Irish gypsy" and "dearest heart."
