Trumpism is simply the cherry on top of a dedicated plan that favored partisanship.

This is not news, it is well known, and public facts (60 years) https://journals.plos.org/plosone/article?id=10.1371/journal... https://www.pewresearch.org/short-reads/2022/03/10/the-polar...

The core plank of the Repub strategy has been to eschew bi-partisanship. It is the home of the Tea party movement, because it kept feeding its base red meat, and then never actually delivering. Trump is lauded by his base, because he treats the political theater as reality.

Please remember, during Trump 1, liberals and centrists reached out constantly to the Republican rank and file, and never made progress. You cannot overcome a media and political machine built to prevent such progress and dialogue.
