While it probably is politically motivated, not every building that every president ever lived in needs to be preserved.
The home that John Adams had in Boston is long gone but his birthplace and the family house still exist.
Yep. Tempest in a teacup, a dirty teacup.
Thank you. Geesh. Do we have to save every damn place someone was ever in? Feel the same way, frankly, about roadside memorials, and more general ones too. Does everyone at every place have to have a memorial? I can think of a few local accidents that are interesting and sad, but in the old days people moved on instead of holding it aloft in perpetuity, so we have no memorials for them.
