Why is it that the Democrats / Liberals / Progressives always express a fear that the Republicans will behave the way they do?
With the Gubernatorial seats gained by the Republicans, the Democrats were expressing a fear and concern that the new redistricting that will occur will be "gerrymandered". How about we take a look at how the districts are set up in a state whose governorship is traditionally Republican vs one that is traditionally Democrat and see if and where gerrymandering occurs.
Texas Congressional districts are all pretty much in block format. The state divided into districts by population without reference to the prevailing political affiliation of the populace.
Massachusetts Congressional districts on the other hand, are a bit more artistically drawn. This one looks a lot like somebody through paint balloons at a wall. The 4th Congressional district is particularly interesting.
Less there remain any doubt as to where gerrymandering of congressional districts occurs, just look at CA 38th Congressional district. If you believe there was no gerrymandering in the setup of that district I have some carbon credits to sell you.
Whenever the Democrats have an outcry about what the Republicans might do, you can usually be sure that the Democrats have already done it.
