It is very impressive that it is the “deplorable” supporters of Trump who are investing, which indicates a much greater degree of support than the affluent elites who donate to the Democrats.
It also suggests that the Democrats plan to cripple the Republicans with lawfare (which is similar to how authoritarian parties in the third world deal with opposition), is being perceived by more and more Americans as anti-democratic and and un-American. The Democrats might do better to fight with Trump on issues rather than arguing that Trump is evil and need to be cancelled. America was founded by people who were “cancelled” in their previously countries, and running a platform of “cancel culture” may prove counterproductive.
