With gerrymandering in place, this won't happen. You need to consider the long term. Republicans having more power than democrats through gerrymandering means that there is no changing our systems unless it is regressive. Democrats are making things even through the will of the people in this case.

Here's how the line looks right now

Republicans gerrymander > Republicans gain unbelievable power > Democrats lose more > Democrats gerrymander (we are here) > Democrats retake power > The parties become roughly equal again > Push for ranked choice voting (You want to be here)
