Increased Political Polarization Ahead
Open seats are shifting power from general electorates to primary voters — and rewarding ideological alignment over pragmatism.
A wave of congressional retirements is reshaping who holds power in American politics. As incumbents depart, decisive influence shifts to primary electorates in both parties, accelerating ideological sorting and thinning the center in ways that may make today’s dysfunction look comparatively restrained.
Lisa Lerer’s New York Times report on the unusually high number of congressional retirements — 63 members so far — frames the exodus as a story about threats, dysfunction, Trump’s continuing grip on Republican primaries, and generational impatience among Democrats. Go to Ballotpedia for a list of retirees from the House.
But the deeper question is not why members are leaving. It is what replaces them. When incumbents depart, decisive power shifts from general electorates to primary electorates. And primary voters in both parties reward ideological clarity and factional loyalty more than coalition maintenance or legislative pragmatism.
This dynamic is visible not only in House retirements but in marquee statewide contests. The two Texas Senate races are a revealing test. On the Republican side, whether the nominee resembles a John Cornyn–style institutional conservative or a more combative, Trump-defined figure such as Ken Paxton will signal how fully MAGA loyalty has become the entry ticket to viability. On the Democratic side, the contest pits U.S. Rep. Jasmine Crockett, a high-profile Dallas congresswoman known for her combative, base-energizing style and emphasis on turnout, against State Rep. James Talarico, an Austin legislator with a reputation for coalition-building and a more traditional electability-focused message — making the primary a clear illustration of the tension between activist priorities and broader general-election appeal.
A Paxton versus Crockett outcome for the general election could be viewed as the canary in the coal mine test for future politics. It is not clear either party wants to win this race.
Arizona offers a parallel signal. The recent departure of a comparatively moderate Republican candidate, Karrin Taylor Robson, narrows the field and may strengthen the lane for overtly MAGA-aligned contenders.
The House map reflects the same structural pattern. In deep-blue districts such as CA-11 (Pelosi), NJ-11 (Sherrill), and several Chicago- and New York–based seats, retirements remove institutional stabilizers and empower activist-heavy primaries. Additional examples include MD-05 (Hoyer) and CA-26, where open-seat volatility favors energized ideological factions. In ME-02, a highly contested district, the departure of a Jared Golden could result in the nomination of a left wing Democrat and the flipping of the seat.
On the Republican side, deep-red districts such as GA-14 (Marjorie Taylor Greene), TX-19 (Jodey Arrington), and FL-02 (Neal Dunn, retiring), along with open or newly unanchored seats including NE-02 (Don Bacon, retiring), NY-21 (Elise Stefanik, retiring), FL-16 (Vern Buchanan, retiring), and NV-02 (Mark Amodei, retiring) — and even R-leaning but competitive terrain like TX-22 (Troy Nehls) — collectively illustrate how retirements and structurally safe primaries are intensifying incentives to compete on ideological purity, turning many of these contests into intra-party races to demonstrate the strongest alignment with MAGA-oriented voters rather than broader general-election adaptability.
What qualifies as “leftward” or “rightward” drift differs by party. Among Democrats, movement left is defined less by rhetoric and more by issue alignment: Medicare for All, Green New Deal–style climate frameworks, a harder line on Israel, and calls to abolish or significantly defund ICE or police institutions.
Among Republicans, the central sorting variable is allegiance to Donald Trump, with reinforcing signals on immigration maximalism, skepticism of Ukraine funding, tariff advocacy, and willingness to nationalize cultural confrontation. In both parties, drift means tighter alignment with activist issue clusters rather than district-specific cross-pressure.
Across roughly twenty structurally revealing open House seats, many are structurally incentivized toward outward ideological movement relative to the incumbents they replace. Because this sorting dynamic is occurring simultaneously in both parties, polarization intensifies even if chamber control changes hands. The center thins while the activist wings thicken. Today’s Congress may appear dysfunctional. Compared to the more ideologically sorted institution emerging from these primaries, it may eventually look comparatively restrained.
Authors Note: The way out of this mess is in my view the formation of a third party, which could become viable very quickly if the third party concentrated on winning seats in the House of Representatives.

The blog also covers personal finance and investments. Sometimes the material can get really technical. See this article about how to conduct statistical tests on PE ratios.
Most blogs are concentrated on a narrow set of topics. The real strength of this blog is its ability to analyze problems by combining information and methods developed in different fields. The most recent example of this is a paper on UNH valuation, which incorporates the author’s expertise as an investor and an economist with a finance background with his expertise on health care policy.
