Lyle Denniston writes Kucinich Seeks to Get on Texas Ballot (I expect this application to fail) and Court Appeal Set on Promo of Campaign Film (about the Citizens United case). Lyle links to the notice of appeal, which answers one of the questions I raised earlier about the scope of the possible appeal. It will not include another challenge to the corporate PAC requirement, at least not at this stage.
Also at Scotusblog, my former student Scott Street offers this analysis of Lopez-Torres.
