Not everyone fell for the scam. One lawyer told Bloomberg News he heard a pitch from Rothstein, but decided not to invest $1.98 million, with a promise of $2.7 million in 90 days, after Rothstein refused to let him meet the clients, see documents or meet the attorneys who supposedly worked on the cases.

But Bloomberg reports that neither Bush nor Florida Gov. Charlie Crist had any problems accepting campaign contributions from Rothstein. The Republican party also enjoyed Rothstein's largesse.

Now Rothstein's partner, Stuart Rosenfeldt says he believes $500 million of the investors' money might be missing.

There's a lesson to be learned here: Don't take the promises of investment salespeople at face value. If it sounds too good to be true, check out the details for yourself. As for politicians, most of them are too much in need of money to worry about their contributors' business methods.

It's too late for this revelation to embarrass form President Bush. As for Gov. Crist, he's trying to distance himself from Rothstein, according to The Palm Beach Post. We'll see whether he returns Rothstein's money.
