Here are most of the maps I've created with this tool. Most if not all use the multiselect tool to change the margins of whole states, watching counties flip based on how much.
1972 senate election margins merged into 20202020 as 1920 (but inverted)2020 as 19322020 as 19362020 as 19402020 as 19442020 as 1948 (all Thurmond votes are given to the GOP)2020 as 19642020 as 19762020 as 20082020 as 20122020 but gubernatorial statewide margins are swapped with presidential results for relevant states2020 but senatorial statewide margins are swapped with presidential results for relevant states2020 but statewide swings are doubled from 20162020 but gubernatorial results are swapped with 2019 and 2021 for relevant statesIt would take a lot of work, but by adjusting both margin and turnout by county one can manually convert the shuffler into a decent approximation of any election from 1960 onward (excluding 1968 and maybe 1992). First adjust the margin, then adjust the turnout to get the closest raw vote margin from a county of the relevant election, do it for all of the counties of the country, and save as a .JSON file. I could do this if I wanted to but I don't think there's any demand for it.
