They should consider themselves lucky that those tyrannous liberals of muh big cities are nice enough to not gerrymander their districts into oblivion like virtually every Republican state does.
They already can thank the voters statewide for preventing gerrymandering by the state legislature. Several years ago the voters amended the state constitution to take redistricting away from the state legislature and put in the hands of an independent redistrict commission.

It results in such things as having a ratio of 12 R to 4 D in a state where it could have been 8 R to 8 D, but there is no way to consign any voters into oblivion. I understand your anger, but anger often pushes people into saying irrational things.
