I meant to post something several weeks ago about the Supreme Court's outrageous decision striking down limits on corporate spending on elections, but other events overtook my efforts.  The best explanation of the decision and the issues I have seen comes from my colleague Geoffrey Stone, a leading First Amendment expert.  Senator Feingold (Wisconsin) has a straightforward commentary.  This statement is quite fair about the import of the decision and about its radical character.

It is obviously a disaster for a country that, qua putative democracy, is already a mess.  It's hard to imagine that the U.S. could become more of a naked plutocracy than it already is, but I guess we're about to find out.
