Yes, it's a puzzlement!
Here's the nut graph from a fine article from Froomkin on how the banksters -- and I know this will surprise you -- own Capitol Hill. On cramdown:
In March 2009, after the House Democratic leadership made a "herculean effort," Miller said, the cramdown measure passed the lower chamber 234-191.
But in the Senate, thanks to ferocious bank lobbying -- and a puzzling lack of support, if not outright opposition, from the Obama administration -- it was defeated by a wide margin, with the bill falling 15 votes short of the 60 needed to cut off debate and move to a final vote.
BWA-HA-HA-HA-HA-HA-HA!!!! "A puzzling lack of support."
Stop it! You're killing me!
