Findlaw has posted my commentary based upon Judge Alito’s questioning of the Warren Court reapportionment decisions of the 1960s. A snippet:

In light of all the different criticisms that might be – and have been – made of “one person, one vote,” it is hard to know what to make of Judge Alito’s 1985 comment. So the Senate ought to ask him a series of follow-up questions to figure that out.
Senators should begin by asking whether Alito still holds that view. Another question (relevant in many contexts besides election law) should be how strong his respect for precedent is: If he does disagree with decisions, how quickly would he vote to overturn them?
Most importantly, Senators should probe whether Alito questions the Court’s reasoning, its strict equal population remedy, or both.
Perhaps he agrees that Court intervention was necessary to end the practice of grossly malapportioned districts, but also believes the Court’s strict one person, one vote principle went too far in remedying that problem, and that mild deviations from “one person, one vote” might be acceptable.
This view, depending on how Alito expresses it, likely would allay fears of some Senators about whether Alito’s views are outside the mainstream on this issue.
But perhaps, as Senator Biden suggests, Judge Alito would prefer to return to the days where state legislatures could restore malapportioned districts–potentially leading to the biggest power grab through redistricting that we likely would see in our lifetimes.
That view is far from the mainstream, and would offer a principled basis for Senators to oppose Judge Alito’s confirmation, and perhaps even filibuster his nomination.
