Yeah, like 1920, one of the highest water-mark elections for the GOP (due to the Panic of 1893, blamed on Cleveland). I noticed some Southern states swept in Republicans, but due to rodent fraud, claimed “Dem wins”, but were overturned, though many weren’t seated until near the end of that Congress (states like KY, for example, elected a 6R-5D GOP majority, and then no GOP majority again until 1928, and then after that until 1994).
I noticed a many of the GOP congressional victories in Southern and border states back in the late 19th/Early 20th were “contested”.
