I found the thing with Spencer alarming - sudden swervings like that are not the sign of a healthy individual. Maybe he always was more liberal than I thought but if so I've been laboring under a misapprehension for a long time. I favor the "he changed" theory but if it's true I do not know why.
So then we agree...
My guess is living in LA, Charles also always had liberal friends and business associates. He reverted back due to group pressure. Everyone can be unconscious of this. You move a little bit each day
