Gerrymandering is not what’s wrong with American politics

… The most important influence on how members of Congress vote is not their constituents, but their party. This makes them out-of-step not only with the average American — the “broad-based public opinion” that Obama mentioned — but also, and ironically, with even their base. Members are more partisan than even voters in their party.

The easiest way to see how little constituency matters is to compare how representatives vote to the partisanship of their constituents. [cont.]
