From the Centre College Alumni Survey.
I asked "Is there a place, besides home or work, where you regularly spend time socializing?" This is a test of the "third place" idea, derived from the work of Ray Oldenberg.
I have noticed that coffee houses have a strong tendency to be left of center and Democratic. I don't think there is a distinctly Republican third place, but my guess is that the country club comes closest.
In the alumni survey, 138 said they socialized at the country club, while 164 socialized at the coffee house, out of about 1400 respondents. There was a 10% overlap between the two groups. The party ratio between the two third places:
Country club: Republican 54%, Democrat 30%
Coffee house: Republican 17%, Democrat 65%
(By the way, of the overlap group, 2/3rds are Democrats.)
