Excellent point . Richardson is toast. Los Alamos is what destroys him politically. DNC will never put him on the ticket.
Even if Wen Ho Lee sues and wins, Los Alamos won't hurt Bill Richardson because it happened before he was elected NM governor. Richardson would use the, "that's old news" defense.
I don't think Richardson is running for President. He's running to be Hillary's VP, (even though his resume is far more impressive than hers.) I read him described as a "moderate liberal populist", a description that would play well in a national election. But no way will the Soros funded wing of the DNC allow Richardson to be the party's nominee.
