Because, as David Horowitz (I think) once said, the issue is never the issue; the issue is always the revolution.
In this case, Horowitz’s comment can be interpreted as the end goals of Progressivism. Waxman probably cares very little for his own personal power, for power’s own sake. He does care about how he can use that power to advance his agenda and ideology, in service to his cause. And Congress is increasingly irrelevant - by intent/design - in doing so.
So like I said, the Exec Branch is now the place where the agendas will be advanced. It’s admittedly much cleaner way of operating. All strong executives, ones with the ability to rule by fiat (EO) are. Congressional power was a useful tool, but it was also very messy and unpredictable ..
Is that it?
Could be. If so it’s worse than I imagined, rather than dealing with greedy, power mad bastiches we’re up against True Believers.
Every one a spiritual cousin to a suicide bomber.
