This interesting analysis in Brennan Centre for Justice is by Michael Li. Here is an excerpt:

This fall, congressional districts around the country will be redrawn based on the 2020 Census. With the For the People Act, Congress has a once-in-a-decade chance to replace a murky and abuse-prone process with one that is fair, transparent, and inclusive.

The bill, which was passed by the House this month and will soon be introduced in the Senate, would strengthen protections for communities of color and ban partisan gerrymandering. It would also enhance the ability of voters to challenge racially or politically discriminatory maps in court, require meaningful transparency in the map-drawing process, and mandate the use of independent commissions to draw maps.

Packaged together in one bill, the reforms are the most significant effort in American history to rein in gerrymandering and other abuses that have long plagued congressional redistricting. But with the start of redistricting nearing, the window for Congress to act is closing.
