One man one vote ruling could alter the political power of cities

Seth Lipsky:

The impact could extend way beyond the Lone Star State, shifting political power away from cities.

Particularly cities with relatively high, non-voting immigrant populations like — oh, say — New York.

The case has the potential to require authorities to strip away during the redistricting process population that isn’t eligible to vote — undocumented aliens, felons, children.
...

Not just upstate. Blum reckons the case could lead to changes in city councils, too. He speculates that council districts in such big cities as New York, Houston and Chicago are among the “most malapportioned” in the country.
...
Slate.com is already suggesting that a victory by Blum’s clients (two Texas voters who feel underrepresented) could mean “more Republican districts.”

This is because most states apportion districts based on total population, which, Slate says, “includes noncitizens, children, felons and others ineligible to vote.”

It would also lessen the impact of illegal immigrants on the political process.  The argument makes sense.
