I believe that Watching the Presidential debates in Elm Haven was intended to be a coda or postscript on what happened to the Bike Patrol characters from Summer of Night.
The chapter on Mike O'Rourke is almost a coda inside a coda as it completes his journey post Children of the Night.
I really enjoyed Watching the Presidential Debates, much more than A Winter Haunting, and was very disappointed that it wasn't included in the Sub Press limited edition of Summer of Night.
