Double incorrect premises. The article says that Trump escalated the feud. Ha. Convenient that the author failed to state that RYAN started things when RYAN failed to endorse Trump in the first place. As usual, all the blame falls on Trump, rather than where it belongs — with RYAN.
All of these pundits and media personalities would fail miserably at Root Cause Analysis.
"Pundits?" Rather dolts with illusions of relevance. Much of what they consider relevant contemporary concepts have always confused parallel effects with actual causation. There is nothing more obnoxious than a confused simpleton with strong opinions. But that is most of what you read or hear today, passed off as the result of analysis.
