How do tennis fans vote in the USA?

[Rockefeller GOP]

Tennis fans are usually upscale in education. In the 1950s that would have been strongly Republican. Today that would be lean Democratic. They are usually also above-average in income.... but in 2008 that mattered little. More urban? Tennis seems to have rather few rural Southern fans (contrast NASCAR fans, who would be decidedly right-wing).

Lean Democratic. Liked Ike, voted Obama.

 
gray -- did not vote in 1952 or 1956
white -- Eisenhower twice, Obama twice
deep blue -- Republican all four elections
light blue -- Republican all but 2008 (I assume that greater Omaha went for Ike twice)
light green -- Eisenhower once, Stevenson once, Obama never
dark green -- Stevenson twice, Obama never
pink -- Stevenson twice, Obama once

No state voted Democratic all four times, so no state is in deep red.

I've seen you talk about how income meant little in 2008, and I have to ask why you're referencing a 7-year old stat when a higher income in our last three elections since then (2010, 2012, 2014) has been DIRECTLY proportional to voting Republican.

2008 may look like an anomaly. Higher-than-average incomes usually relate more to formal education and occupational status, and especially to ethnicity and the urban-suburban divide. 

As late as the 1990s, poor whites tended to vote Democratic. That is over. 2008 reflects the strength of Republicans among poor white people (who, by the way, rarely have any involvement with tennis).  Most poor people in America are white, so such may explain more about the electorate than any obvious correlation between income and voting.

Tennis is at least upper-working class (skilled workers), and largely middle-class and especially upper middle-class, in appeal. If I say "lean D" it is because poor white people do not play or watch tennis.

And poor minorities do?  My point is that you have said yourself that the wealthy tend to play tennis at a higher rate; they also vote Republican at a higher rate.  You've also seemed to at least insinuate that tennis might attract a Whiter crowd than other sports (anecdotally looking at highlights on TV and passing tennis courts, I wouldn't have trouble believing that), and combining those two (White + wealthy) gives that random voter a much higher chance of being a Republican than being a Democrat, on average.
