I have written this piece for TPM Cafe. It begins:

Readers of the entire 147-page opinion issued earlier this month by a federal district court striking down Texas’s strict voter identification law as unconstitutional and a violation of the Voting Rights Act might have been too exhausted to realize that the opinion’s very last sentence may be its most important. The court ended its opinion with a dry statement promising a future hearing on “plaintiffs’ request for relief under Section 3(c) of the Voting Rights Act.” That hearing, however, has the potential to require Texas to get federal approval for any future voting changes for up to the next decade, and to make it much more difficult for the state to pass more restrictive voting rules. It may be much more important than the ruling on the voter ID law itself.
