And yet, fixing that problem -- the problem of the ineffectiveness and hyper-partisanship of Congress -- would have so many positive effects for all of our lives regardless of our ideological perspectives that it should be our number one priority as the electorate.
The ineffectiveness and hyperpartisanship of Congress is directly attributable to the ideological perspectives of the electorate.
Also, Congress is not as ineffective and hyperpartisan as you think. It's only on issues that have public attention that they act this way. When nobody is looking they move quickly and decisively.
Eliminating partisan gerrymandering would go a long way.
Less than 10% of congressional districts this year will be competitive (defined as the most recent presidential election margin was within 10 percentage points). Only 41 seats!
I haven’t really seen a realistic plan to do it though.
OTOH, results of elections to congress (house of representatives) looks balanced - total seats gained by each party matches popular vote with deviation < 1%. Which is much better than i expected considering single-seat system leads to advantages for dominant players even without gerrymandering.
Even in my home country, which is european country with proportional system and no gerrymandering, such deviation is higher (< 2%) due to rounding effects.
Gerrymandering is main issue in (some) state elections (e.g. Wisconsin 2018 is egregious example), not federal elections.
The totals are a little misleading because there is partisan gerrymandering on both sides, so they somewhat balance each other out. Courts have also been highly involved in rejecting the most brazenly disproportionate maps, but that may soon change next year due to the newly constituted Supreme Court.
The bigger problem is that it incentivizes partisanship and extremist views in uncompetitive districts because the representative is effectively decided in the party’s primary election, not the general election which has higher turnout and a more representative electorate.
Also the fact that 90%+ of congressional seats are safe except for the occasional primary opponent discourages accountability. Our districts are so distorted, they make no geographic sense. And it means a large percentage of our population is permanently disenfranchised, which dampens voter participation. It really is one of the biggest structural problems of our democracy right now.
