Arthritis/rheumatism is associated with body parts that get stiff, swollen, painful. Arthritis/rheumatism of the brain is even worse. Right?

That seems to be a common thread that Pols share which explains the lack of coherent, logical thought.  When you have an arthritic brain you are limited in what you can do with it. Something they share regardless of partisanship and party label. It's not curable. It is manageable with drugs but you just learn to live with it.
