What does "banning gerrymandering" look like? Who gets to declare what a gerrymander is? What mechanism allows us to determine whether a map is "fair"?
California "banned gerrymandering" years ago and this was what they produced, a map where Republicans can win nearly 40% of the popular vote and win just 17% of the Congressional seats.
Every single appeal from a Liberal for neutrality or de-escalation is a thinly veiled demand that we unilaterally disarm ourselves and let you win.
Republicans 30 years ago may have gotten on board with Democrats in banning gerrymandering, but not anymore because we now see you people for what you truly are.
Democrats are no longer a debating partner trying to push us towards a mutual shared goal that benefits us both. They are an enemy to be defeated by any institutional or legal tool possible.
This is the most common sense thing ever, but Republicans block it every time.
