While socially problematic, residential clustering of minority groups is politically advantageous. Uniformly distributed minorities risk getting 0% of seats even with significant voter share, as they can't form a majority in any single district. Clustering allows them to secure representation by creating districts they can win.

Because the census counts all residents regardless of legal status, blue states experiencing population decline due to citizen out-migration can maintain their congressional seats and electoral votes. This creates a powerful political incentive for Democrats to resist mass deportations, as it directly impacts their national power base.

Recent census data reveals a significant shift in U.S. internal migration. High housing costs are pushing residents out of traditionally fast-growing states like California, while more affordable states, including some in the Midwest, are experiencing population growth for the first time in a decade.

Politicians are fundamentally incapable of drawing fair electoral boundaries due to an inherent conflict of interest: they want to ensure their party wins. Using a randomly sampled citizens' commission, as Michigan did, removes this conflict. This allows ordinary people, guided by a sense of fairness, to create equitable maps where politicians and courts have failed.

Voting data from the NYC mayoral election reveals a stark divide. Residents born in the city largely rejected the socialist candidate. However, his victory was secured by overwhelming support from people who had lived in the city for less than 10 years, suggesting newcomers are more receptive to radical policies than longtime New Yorkers.

Mayor David Holt argues the perception of a polarized America is misleading. He believes a 70% moderate majority is silenced by an electoral system, particularly closed primaries, that empowers the extreme 15% on each side to select polarizing candidates.

The political divide is no longer just about policy; it's a fundamental separation of information ecosystems. Red and Blue America use different social media, consume different news, and don't interact, creating worldviews as different as North and South Korea. This digital separation precedes any physical one.

In gerrymandered districts, the primary election, not the general, is the real contest. This system empowers the most extreme voters who dominate primaries, leading to the election of highly polarized officials who are unwilling to compromise, creating legislative gridlock and fueling political division.

With over 90% of congressional districts being non-competitive, the primary election is often the only one that matters. Buttigieg argues this incentivizes candidates to appeal only to their party's extreme flank, with no need to build broader consensus for a general election.
