At Balkinization, Abbe Gluck (Yale) has this interesting long post on the cases challenging the federal health care exchanges' authority to give subsidies: How Congress Works (and the ObamaCare Subsidies Lawsuit). This is the best argument in favor of the subsidy power I've heard, and confirms that Professor Gluck is doing some of the most interesting work in statutory interpretation around (see here, for example).
For background and counterpoint on the subsidies cases, see here from Jonathan Adler (Volokh Conspiracy), here from Sean Trende (Real Clear Politics) and here (my comments).
