As it stands currently, it's important to disambiguate the nuance that the Senate currently has enormous power while the House has very little real power.
In the current context, gerrymandering only serves to prevent impeachment at this point, but it could permit even more extreme executive-dictated, legislative rubber-stamping. In the long-term, it would stack the deck for partisan cheating.
Perhaps an amendment is needed to insist on independent, non-partisan district map commissions for every state at the federal level.
PS: I used to live in Greg Casar's ultra-salamander TX-35, but now it bypasses me down I-35 with an umbilical or tiny body from SATX to ATX. TX-15 ® an TX-28 (D) run through my ZIP Code now.
Perhaps every state should be divided by the same, open source, simple and fair algorithm that creates deterministic centroids of people of close to the same population to maximize political competition, not minimize it.
This is something too important to be left to political hacks of some states but not others who seek to cheat at elections to favor incumbents.
But this gerrymander would just be one more on top of hundreds of others. The fact that "congress" agrees with the president is just another symptom of the fact that the entire system is fundamentally nonresponsive to the will of the people.
That a Republican Congress isn't checking a Republican President isn't evidence of a lack of checks and balances.
And points to why the President is pushing so hard for Texas to gerrymander additional Republican seats into the House...
