I've always said that Arnie is a Democrat.
He claims to be a Republican, but he's not. After winning the California governor's seat through his popularity, he proceeded to act like a Democrat: hiking taxes, closing schools and state parks, and telling everyone to drive less while flying back and forth from his home in LA to Sacramento every day.
Now he's proven he's a Democrat. Arnie admitted today that he has fathered a child by a housekeeper 10 years ago, while he was married to Maria Shriver. Only Democrats do that.
I figure Arnie's next step is to run for president. For a democrat, cheating on your wife and fathering an illegitimate kid is a resume' enhancer.
