"Redistricting" isn't a new recent thing, it is a process done by state legislatures to state and federal legislative district every decade that has been used for both personal and partisan advantage since the founding; the word "gerrymander" was coined in criticism of a particular instance in 1812.

I think there is a primary-related problem going on right now that could change historically held positions on the value to financial backers interests of uncontested general elections.
