The most rediculous example of partisan gerrymandering in recent memory occured in Texas when the Dems were required to be in the state when it was done so they camped out in Louisana and Dick Armey (I think it was) used the sate police to track the dems down and then they were tricked into entering the state and... bango!!!
But seriously, gerrymanderin' only insures that folks, right or left, can be as outrageous as they want and the more extreme they are they better chances are that they will be re-elected??? So when they get to Washington it's gridlock...
Tell ya'll what... Fair disrticting where each party has a reasonable chance to win will end the extremes and end the gridlock in Washington... Right now there is no incentive for anyone to compromise if they know that by not doing so means they will keep their job???
