From a WashPost editorial today bashing partisan redistricting:

Redistricting is already playing a deeply corrosive role in American politics, allowing politicians to choose the voters who will maintain them in power. American legislative elections are dramatically noncompetitive; the incumbents nearly always win -- except, that is, when a district has been set up specifically to target someone of the other party. The result is an ever more polarized Congress unaccountable to the voters who nominally elect it.

If most Congressional districts are forced into uncompetitive races, and most Congressional races are therefore decided in the primary, and most states have closed primaries, then your vote simply doesn't count unless you happen to be registered with the "right" party. Something is fundamentally wrong with this equation ...   ¶ 11:44 PM
