I don't agree with gerrymandering for political power. I understand the response though to Trump/Abbott/Texas actions.
I'd prefer a federal law under the Constituition Article I, Section 4 power of Congress to:
#1 Establish that all states must use non-elected, bi-partisian election commissions required to draw district lines based on population density, natural barriers (moutains, rivers, etc.) and established civil boundaries (villiage, town, city, county, etc.) lines.
#2 Once set post Census, States cannot redraw lines.
DEM and GOP gerrymandering is a bane on the Republic.
