Rubin and Clinton bailed out Long Term Capital Management (a brokerage) with government (taxpayer) money. Had LTCM gone done (as Enron has) then a number of other brokerages would have suffered large losses from their business with LTCM. One of those was Goldman Sachs. Surprise, surprise, Mr. Rubin was a former partner in Goldman Sachs. Saving LTCM with taxpayer money saved Mr. Rubin's former partners from eating millions in losses. Mr. Rubin went back to Goldman Sachs when his days with Clinton were done.
Fast forward. Mr. Bush's administration did not lift a pinky for Enron. Enron (Kenneth Lay) contacted Administration officials three times in the week before Enron declared bankruptcy. Obviously, he hoped for something that would forstall the collapse. He got nothing. And Enron filed for bankruptcy the following week.
Had Bush bailed out Enron, like Clinton did LTCM, then the Democrats would have raised a scandal to high heaven -- for cronyism and insider-dealing writ large. But all those 401k's would have survived. Since Bush did nothing the Democrats now raise scandal because there are "oilmen" in the White House and Enron is an energy company. And Bush has actually even talked personally with Kenneth Lay when he was Governor of Texas (gasp!).
Essentially, the Democrat position is if you did nothing you are guilty of scandal and if you did something you are also guilty of scandal. You are guilty because of who you are. And you are guilty because you haven't lived your entire life sucking off the government teat.
