http://www.democraticunderground.com/discuss/duboard.php?az=show_mesg&forum=132&topic_id=7881371&mesg_id=7881371Team Obama, after all but offering SecState to Senator Clinton, is expressing EXASPERATION with the Clinton camp for the difficulty in getting a clean vet on President Bill Clinton’s many entanglements. “The ball is very much in her court, but the president's finances have been a major point of sensitivity from day one,” a Democratic official said. (“Day One!”)
“Given that everyone's mystified by how deliberately public the Clintons have made this once secret process, the assumption is either that the Clintons are trying to use the public buzz to steamroll their way in, create a sense of inevitability that overcomes those concerns, or that it's just a matter of time before they … satisfy vetting somehow, some way.Otherwise, after all this speculation, there’ll be a permanent dark cloud hanging over her finances. …
But generally the sense among the no-drama Obama world is: This is well on its way to winning best Oscar for drama.”
