Political scientists have long said that there's not a lot of evidence for a change in macro outcomes due to gerrymandering. In most scenarios, if anything, gerrymandering makes sitting politicians on both sides more safe. It's really hard to actually tip the balance such that one side gets significantly more seats because if you spread your supporters out efficiently (51% your party) and then cluster the other party, you get a bunch of weakly held seats. However, if you want safe seats, you get fewer of them.
