Scouts case is a compilation of other cases. Actually it was submitted by Fairholme and Pershing appears as amicus curiae. Sound familiar? This is a summary of the bullet points.
Compelling arguments at @SCOTUS, I've also pointed out: -The word "may" -The Incidental Powers are preceded by the phrase “authorized by this section” -Act “in the best interests of the Agency"doesn't mean"the Govt" -FnF "kept on the brink of insolvency"to force draws.#fanniegate
