Obama, his wife, William Ayers and his wife all have a huge history that dates back to when Obama's wife worked with them. They have done business, politics and much more together. One would have to be naive that Hussein did not know the politics of those who his wife was working for/with an just how radical they were.
We are talking weather underground here, killing US citizens with no remorse, about as bad an association as things could possibly get for a potus candidate. Obama is Manchurian IMHO.
