Wikipedia's summary has this prophetic quote from Senator Everett Dirksen of Illinois who led an unsuccessful fight to pass a Constitutional amendment allowing unequal legislative districts.
Dirksen warned that "...the forces of our national life are not brought to bear on public questions solely in proportion to the weight of numbers. If they were, the 6 million citizens of the Chicago area would hold sway in the Illinois Legislature without consideration of the problems of their 4 million fellows who are scattered in 100 other counties. Under the Court's new decree, California could be dominated by Los Angeles and San Francisco; Michigan by Detroit.."
That is exactly what happen to CA!
The irony of this particulate case is it prove the fallacy of the idea that the dictates of the Federal employees in black robes could be controlled with future amendments.
It took a decade and after that decade we had finally came within 1 state of a 2nd Constitutional convention over this edict. But by the end of that time too many of the States had been taken over by the power greedy urban centers.
Leftist urban areas who of course had no interest in allowing the rest of the State to have a veto over their abusive self-serving manipulation of the common state goverment.
The system the Advocates of the Federal injustice system claim to exist checking their tyranny failed catastrophically yet again.
