When does gerrymandering take place?
To try to secure more delegates for your political party. Carve up the opposing party’s strongholds of support into different strongholds of support for your party, and you’ll have more representatives from your party elected. It’s a shady practice that I find reprehensible. Sorry, I thought you were asking “Why…” for some reason. Gerrymandering can take place almost anytime; the politicians doing it just need to argue that a shift in population distribution justifies redrawing district lines. Usually, though, it takes place after the national census, which is every 10 years.
