I think it’s wise not to discuss politics with her. When it gets down to core issues, I have friends of different political persuasions(not family) but it reveals what is really important to them.
Actually, she lives for her TV. Her husband has died, her children cannot be there 24/7...so it’s the TV and the core channels only. These are her daily friends and she thinks like them because she spends her days with them. She needs the world to come to her and it does...with Joy and Whoopi on the view and the newscasters she has always listened to. She even likes Ellen, my SIL is a lesbo, so that’s ok to her.
