I could remember being shocked to learn that Silicon Valley was a big supporter of Clinton back in 1992. Clinton was a socialist, and anti business, yet all the entrepreneurs were for him over Bush 90/10.
You’ve heard the saying that “the rich get richer”? Those businessmen aren’t stupid. They know that if they vote for and support Demonrats with their money, they will be left alone at tax time. If they come out for Republicans, they will be harrassed to death. Since they are already wealthy, what do they care about what happens to America and its culture?
