Who Knew? Lovebird Dick Nixon

An exhibit at the Richard Nixon Library - 200 years of presidential love letters and pictures - reveals the passion behind the power, reports CBS News Correspondent Bill Whitaker.

For instance, who knew that Richard Nixon's stiff-as-a-board persona masked a randy romantic?

"When the winds blow and the rains fall and the sun shines through the clouds," he wrote to then-schoolteacher Pat Ryan, "that nothing so fine ever happened to him or anyone else as falling in love with thee, my dearest heart."

Says exhibit curator Olivia Anastasiadas, "We believe our leaders to be completely interested in politics, foreign affairs, domestic affairs - and not necessarily the affairs of the heart."

Lovebirds Ron and Nancy Reagan exchanged Snoopy Valentine cards. Dashing Dwight Eisenhower grew weak-kneed around young Mamie. President Woodrow Wilson was so enthralled with Edith Galt he wrote two love notes a day of stolen kisses on her lips and eyelids.

And there's more.

Stern John called called Abagail Adams "Miss Adorable." Rough Rider Theodore Roosevelt was so incurably lovesick for first wife Alice he wrote her "I could not live without you, my sweet-mouthed, fair-haired darling."

When she died three years later, following the birth of their daughter, the heartbroken president never spoke of her again.
