In the process of setting electoral districts, gerrymandering is a practice that attempts to establish a political advantage for a particular party or group by manipulating district boundaries to create partisan advantaged districts. (http://en.wikipedia.org/wiki/Gerrymandering).
This practice is well established among both Democrats and Republicans. Sometimes they even cooperate, so that a Republican has a nice safe district, while the parts that would have normally been in his district now make up an equally safe district for the Democrat. You pat my back, I'll pat yours. All you have to do is follow the money.
Anyone who thinks either party gives a shit about regular people or America is clueless. They are all in it for themselves. SSDP, same shit, different party
Politicians are like diapers. They need to be changed often, and for the same reasons. Next time when you vote, vote for the first person that isn't a Democrat or Republican. An remember to change them too when they get shitty.
