What's so sordid about Soros - at least from the perspective of the right? I could understand the left loathing him more - due to his involvement in the financial sector. I have a tendency to view him positively because of his support of the concept of the Open Society and his espousal of Popper's political project. I don't know a huge amount about him beyond that but this alone makes me lean towards regarding him as a force for good - even if the idea of billionaires spending money advancing political agendas is deeply troubling on the whole.
