Even if the Democrats take the House and the Senate this year, and pass a new Voting Rights Act, there's no reason to believe it will have any effect, since it will be immediately vetoed by the President. So I'm not sure your expectations are in line with reality here.
26 - 28 I expect the Democrats to investigate, write reports, block nominees, and occasionally pass legislation they know will be vetoed but otherwise have no effect. I hope everyone is ready for reality here.
