Your guess is as good as mine. I'm thinking about 1860... From AP earlier this week:
The Senate may be the place for some former first ladies, but President Bush on Thursday categorically ruled out a run for office by his wife, Laura Bush.Heaven forbid a woman be allowed to speak for herself. And there is no way Laura could be interested in both literacy and the Senate. It's Bush's world, no one can do more than one thing at a time.
"She's not interested in running for office. She's interested in literacy," Bush said during an appearance at JK Moving & Storage.
The topic came up as the president took questions from his audience after a speech on the economy. A woman asked if Mrs. Bush would ever run for Senate from the first couple's home state of Texas, and Bush responded "never" - twice.
He also declined the woman's plea that he at least ask Mrs. Bush if she might be willing.
"She's a great lady," the president said. "She's not interested in running for office."
