There’s clearly a lot more to say about this re-redistricting controversy. For the 
moment, a couple quick points.
First, Texas and Colorado may not be the only states where this happens. New Mexico, where the Dems are in charge, is considering doing more or less the same thing.
Second, this re-redistricting is every bit as unprecedented as it seems. As noted yesterday, states sometimes redistrict because of voting rights law suits. And there were a spate of court-ordered redistrictings during the middle 1960s, growing out of the so-called one-man-one-vote cases (see Baker v. Carr, 1962). But doing a second redistricting for partisan reasons during one census cycle hasn’t been the norm since the 19th century. The last instance of it, according to a redistricting expert I spoke to today, was in Washington state in the 1950s — and the tactic was unheard of even then.
