The fall of John Cornyn mirrors the fall of the Republican party
The Texas senator was emblematic of the era between Reagan and Trump, as Republicans shifted from the party of business to a cult of personality

TL;DR
- John Cornyn's defeat in the Senate primary by Ken Paxton, endorsed by Donald Trump, signifies a major shift in the Republican party.
- Cornyn represented the 'steady conservative institutionalist' wing, which has been supplanted by Trump's 'cult of personality'.
- His loss reflects the broader shattering of the Republican party's foundations laid by figures like Ronald Reagan and the Bushes.
- Cornyn's career was closely tied to Karl Rove and Mitch McConnell, instrumental in building the Republican party's structure and fundraising operations.
- The article suggests Cornyn's attempts to align with Trump were insufficient, as Trump's animosity stemmed from Cornyn's actions, such as certifying the 2020 election.
- Cornyn's rise and fall is presented as a microcosm of the Republican party's transformation from a political party to something else, possibly a kleptocracy.
