I didn't feel the article really refuted the problem of gerrymandering. The Ted Cruz and Cravaack/Nolan shifts weren't cited as examples of where gerrymandering failed to produce the desired result. Gerrymandering might not be a problem when viewed in the context of a single legislative session but the lasting impact will be felt over many sessions.

But the article does make good points of self selected voting districts resulting from people moving in and out of communities.
