Create safe districts, moving the real election to the primary stage, and then give the electorate a doomscrolling-device as their primary information source.
So the primary voters become more radical and paranoid and we wind up with growing proportion of fringe candidates who would lose to a dog if only they weren't safe seats.
Moreover, the growing rural/urban partisan polarization means even non gerrymandered districts that are created by nonpartisan panels or algorithms are frequently left or right polarized. Creating competitive districts would require gerrymandering in many places in the USA.
Missouri Compromise, Kansas Nebraska Act, Nevada, Utah, and the Dakotas' existence, Washington DC not having representation, Puerto Rico languishing
Coincidentally it seems like the rural United States has disproportionate representation and power. I'm sure that has nothing to do with the Republican party not winning popular votes in presidential elections for all but one election in over 30 years
Many solid “red” rural states today frequently elected statewide democrats just a few decades ago.
That’s not even getting into that the claim of Biden as “center right” is based on Overton window shifting. Biden repudiated many of his earlier more centrist positions on DEI (e.g. his anti-school busing activism in the 70s), immigration, abortion, etc to win the nomination. Compare Biden’s platform and positions to the Obama 2008 campaign platform and can you really see it as a “rightward” shift?
