You never know. Mary Todd Lincoln and Nancy Reagan turned to spiritual practices like seances and astrology.
We expect the President to be grounded in practical reality. The First Lady, not so much.
A 2009 Pew Research Center survey shows that 18 percent of American adults say they have seen or “been in the presence” of a ghost. Almost one in three (29 percent) said “they have felt in touch with someone who has already died.”So with 45 First Ladies, 18% is about 8 who, statistically speaking, might really believe in ghosts.
Given that, I'm not the least surprised that a few have held seances or whatever. Astrology is even more common.
