What strikes us about the case, though, is the narrowness of the Supreme Court’s ruling — and, indeed, the prospect that the court may have opened a vast national struggle in respect of the drawing of election districts.
What it ruled is that Texas was within its rights to apportion its election districts according to the total population of each district. What it didn’t do is require that the Lone Star State do so, which struck an uncharacteristic note of humility for the Nine.
You may do this vs. you must. Big difference.
