I have written this piece for MSNBC Opinion. It begins:

A sudden war over redistricting has broken out in Texas and looks to spread across the country, with California, New York and elsewhere considering tit-for-tat Democratic partisan gerrymanders to negate the Republican hardball in Texas. Congress, rather than the courts, is in the best position to stop the upcoming race to the bottom. But even though it’s in everyone’s interest that Congress act, don’t hold your breath….

It is possible the courts will block some of these gerrymanders if it can be shown, for example, that they violate the Voting Rights Act. But the Supreme Court just signaled that it may further weaken or kill Voting Rights Act claims in redistricting cases. With that red flag, and with the court’s decision to allow unlimited partisan gerrymandering, the courts are not likely to get the country out of this vicious cycle.

Congress can stop the madness at any point. The Constitution gives Congress the power in Article I to “make” or “alter” state rules for running congressional elections, including redistricting. Congress could outlaw mid-decade redistricting, require the use of commissions, or set a standard barring the most egregious partisan gerrymanders.

In the current polarized atmosphere in Congress, and with Trump (who would have to sign such legislation) looking to impose “maximum warfare, everywhere, all the time” to preserve Republican power, a bipartisan deal to avoid a redistricting war seems most unlikely. But as the Cold War taught us, détente is better than mutually assured destruction for all the parties. Those who suffer the most are the voters, who should not be packed in or cracked out of districts simply because their party is in the minority.
