What effect did the Supreme Court's ruling in Shelby County v$.$ Holder $(2013)$ have in many states previously required to get preclearance like Texas, Alabama, and Georgia?

Many of these states began adopting convenience voting laws, like drive through voting, same$-$day voter registration, and more expansive opportunities to mail in ballots, to expand access to the ballot for all.

The legislatures in these states have failed to recognize this decision and instead have worked with the Department of Justice to ensure equitable voting laws are in place.

The legislatures in these states have introduced and passed many new laws pertaining to voting registration and access including liming same$-$day registration, new voter ID laws, shorter voting hours, and curtailing voting by absentee ballot.

Many of these states have altered their redistricting process $($i$.$e$.,$ the drawing of legislative districts$)$ to rely on nonpartisan commissions rather than state legislatures.
