Obama raises so much - where is it coming from?

There are indications that Obama is receiving millions of money that needs to be converted to USD. Maybe this is why Obama refuses to release names of those who donate to campaign while McCain has done so. Some estimates are up to 63 million and even possibly more with latest numbers released. He does many things that are in secret that should be of public record. Reminds me of corralory to Einstiens saying when facts get in way of cherished theory (like say evolution) that facts are disgarded. In this case the democratic nominee is lusted over so much his handlers do not want to reveal who and what he really is today.
