Inspiration: I came up with the following part yesterday, and posted it first as a comment here.
July 20, 1969 - NASA lands a man on the moon.
July 18, 1969 - Teddy lands a woman underwater.
A few days bigger gap and there might have been enough ink available to cover both episodes fully.
The moon landing won out, and the U.S. has had to suffer with Teddy for 40 extra years...
The opening analogy came to me as I was writing this post.
Reminder - Ted Kennedy owns a dog he named "Splash". The dog's breed, and I am NOT making this up, is a Portugese Water Dog. Teddy wrote a children's book called "My Senator and Me" from the perspective of Splash.
