It changed when bill and Hillary came to town with no appreciation of where they were.. No respect.
Reagan dressed in suit when he entered the oval office. Bill Clinton disgraced the oval office.
None since Reagan had the respect and honor for the biblical leaning, used by the founders. It’s been downhill since.
I don’t discount those that look further back…to the CIA removing Kennedy. When Eisenhower issued his warning, I think that tells something very significant that has been purposely buried. Presidents just don’t issue warnings like that in our history. I think it was more significant than anyone knew.
