We took Ellie to STL's wonderful children's museum, The Magic House. (Yes, she is officially Madeleine but we all call her Ellie and I'm changing my usage.) I had not been there since our kids were young. It's been greatly expanded and improved. Ellie had a ball.
There was an area devoted to American government. To my surprise, there was a mock-up of the Oval Office. The children could pretend to sit at the president's desk and Ellie took her turn. I think she was taking a call from Putin.
The Constitution requires that the president be at least 35 years of age. A video system lets the kids find out how long they have to wait. I hope it won't be nearly that long (months preferred to years) for a major improvement on the incumbent.
