It was insidious. It was, to them, although they didn't put it this way, similar to the kind of dark Clinton-like conspiracies that Republicans were more wont to accuse liberals of-Whitewater, Benghazi, Emailgate. That is, an obsessive narrative that leads to investigations, which lead to other investigations, and to more obsessive no-escape media coverage. This was modern politics: blood-sport conspiracies that were about trying to destroy people and careers.
The text discusses the nature of modern political narratives, particularly how certain investigations can spiral into obsessive coverage. The author suggests that both sides of the political spectrum engage in creating conspiracies and narratives that dominate public discourse.
These conspiracies function similarly to those previously leveled against politicians, creating a continuous cycle of inquiries and media attention. The author compares this to past Republican claims against Democrats, highlighting how politics has turned into a "blood-sport," aimed at undermining individuals and their careers.
