The law needs to be struck down in the interim, because Congress would never get around to updating it otherwise. Congress had multiple chances to update the formula, but they have been too lazy to do so. The last time congress actually put the effort into updating the formula was 1972.
I disagree that we should extend preclearance to the entire nation. Preclearance would be an unnecessary burden on the local, state, and federal government. In Texas, the vast majority of the preclearance requests are trivial requests such as moving a polling place from a church to a school. That means we have to wait for the slow, federal bureaucracy to approve the request before we can do
any simple task that deals with voting. Areas without any
recent history of voter suppression should not be put through such a burden. Also, the courts are perfectly capable of dealing with cases of voter discrimination. I would also prefer the court system to rule what is voter suppression instead of an executive branch that is prone to
put politics before rule of law.
Voter suppression clearly isn't much of a problem, because no one in Congress feels this is enough of a priority to even talk about.
