Everyone donates to the party that best serves their interests.The Republican Party is the party of the rich and corporate America. That's why those groups give their money to the GOP.Repubs, when they are true to their principles, are the Party of Freedom and the private sector.The Democratic party is the party of the working (middle) class and labor. That's why they donate to that party.Democrats are the Party of Big Government, and they'll soak the middle class with higher taxes to pay for it.The overpaid, spoiled, thuggish public employee unions are in roughly the top 10% of income earners, enriching themselves unfairly with Other People's Money.Beyond that, the Liberal Welfare State, corrupt Wall St. fatcat financial companies like Goldman Sachs, Fannie Mae, Freddy Mac, the Government Monopoly School System, etc. etc.All getting highly prosperous if not literally rich from taxpayer money, all of which gave massive amounts of campaign money to Obama and Dems.
