Politicians can draw fairer election districts − the way kids split a cake

Congress used to increase the size of the House of Representatives routinely, but there hasn't been an increase in over a century. In that time the population of the US has more than tripled.

As long as the current standard of less than a percentage-point variation of district population from the average within a state is maintained, opportunities for partisan gerrymandering would be drastically reduced by a significant increase in House members, since most of the population is concentrated in urban areas; and the more districts there are the fewer options there are for drawing boundaries within that constraint.

If the Democratic congressional supermajority in 2009 had simply increased the size of the House by a relatively modest 200-300 members, it would have been virtually impossible for an absolute minority of voters to capture either the House or the presidency going forward. After the result of the 2000 election, that should have been a top priority. Instead we relived the nightmare in 2016.

No fancy new big-brain think tank shenanigans are required. Just return to what used to be the norm and what the Founders expected.
