"But Darren," some claim, "the Article V hurdle is too high! Things have changed, times have changed, and we need an easier way to make things right!" My answer to that is to change the Constitution to make it easier to change the Constitution, not just ignore Article V because it's (intentionally) difficult.
Of course, if you're an ideologue California Supreme Court justice in arm's reach of the US Supreme Court, that pesky Constitution isn't something you have to worry about for long:
Asked about the doctrine of enumerated powers and whether it was possible to reconcile the limited view of federal power articulated in The Federalist with modern Supreme Court doctrines, Liu demurred. “If I had an answer to that I’d have written a book,” he quipped, observing the question of federal power is an enduring constitutional and political debate. Despite the language of enumeration, he noted, “there are certain economic realities that have shifted our understanding of these words over time,” such as the increasingly integrated economy. Nonetheless he noted that it is a hotly debated proposition whether courts should rely more on founding era understandings or contemporary realities.That's fancy talk for "I'll do what I think is right, the Constitution be damned."
You want a poster child for liberals? There you have one.
