In sports: Russell Wilson, Seattle QB (a hometown favorite)
In movies: I would go with George Clooney. His politics aren't my politics. But he always expresses himself eloquently, and he comports himself with dignity. I have huge respect for that. Plus he married a classy woman.
In music: Sir Paul McCartney and Wynton Marsalis
In politics: Again, I disagree with Barack Obama, but I think he exudes class. Same with the late GHW Bush.
The classiest real human I know is my 87 year old brother in law.
