Nothing. Gop's done nothing so it's puzzling. They'll be blamed for allowing a bailout if/when a draw from treasury happens, and that would be quite a political wound, I would think!
But yet they've done nothing to stop a draw from treasury from being necessary.
Is the TBTF lobbying so successful that it is causing the GOP to go on such a suicide mission as to allow the conditions that will necessitate a draw from treasury? And so successful that there is zero consideration in the huge new tax reform for the GSEs' DTA problem?
I fear I smell another setup. Rather, the final blow from TBTF. They have masterfully arranged things for themselves to work out this way over the last 10 yrs or so.
