When you approach the polls this November to choose the members of Congress you’d like to see elected or re-elected, you will likely have put in some time prior to the election studying up on how your candidates compare to your views. It’s worth noting that there are now websites created just for that reason, such as VoteSmart.org’s “VoteEasy” platform. But it may not have crossed your mind that elected representatives and their political allies in the state legislatures will have pre-selected their voters by creating partisan electoral districts through the manipulation of maps.
