McCain is always wearing a baseball cap..... To shield him from the sun.
It’s the sunburn you get when you’re six years old that does you in decades later. The one place where he did not have to worry about getting too much sun was the Hanoi Hilton.
But alas, everything I’ve read about malignant melanoma is that it just keeps coming back like dandelions until it gets you.
He would be much better served, IMO, if he wore a real hat, say a Stetson Open Road, like Truman, LBJ or Ike. Better protection from the sun and much more stylish.
