intial observation is that this is not the slam dunk either side is making it out to be. It opens the door for congress to make new preclearance legislation that complies better with sec 5 . Of the voting rights act. However ,the court did not invalidate the principle that preclearance can be required . The way i read it ,preclearance has to be updated to recognize the progress made since the voting rights act was adopted .
To me ;the key sentence in the roberts decision is this :

as i recall ;2009 both houses of congress was majority dem . They could've easily acted to correct the concerns of scotus about sec 4 . But they were too busy shoving obamacare down our throats to deal with an outdated clause of a law from 1965.
Now if congress wants preclearance ;they will act to update the voting rights act ;instead of the pattern of re-authorization without any thought.
