I guess this shouldn't come as a surprise. Most people are just now getting to know the name "George Soros", but he has been actively using his billions to not only influence US, but world politics for years. There is very little unbiased historical information outside of Wikipedia, so take the things I am saying here with the proverbial grain of salt.
Soros appears to be heavily influenced by his early life during the Nazi occupation of Hungary:
The Jewish Council asked the little kids to hand out the deportation notices. I was told to go to the Jewish Council. And there I was given these small slips of paper...It said report to the rabbi seminary at 9 a.m....And I was given this list of names. I took this piece of paper to my father. He instantly recognized it. This was a list of Hungarian Jewish lawyers. He said, "You deliver the slips of paper and tell the people that if they report they will be deported."
There is much more at the Wiki link, including his 1992 Black Wednesday participation, "Open Society", "Media Matters", etc. Soros is a devout Leftist and the leading bankroller of all things Leftist. He is also 80 years old.
Edit 0600, 10/24/2010: A telling line from Wikipedia:
Victor Niederhoffer said of Soros: "Most of all, George believed even then in a mixed economy, one with a strong central international government (emphasis mine) to correct for the excesses of self-interest."
