If given the option, which recent US presidential election would you flip?

So I voted Gore > Bush for the butterfly effect/climate change/"the timeline diverged here" reasons along with thinking that by the time the 2016 general came around Trump had already done enough lasting damage that would continue past even had he lost, but upon some more thought I think the margin of victory might matter. If you give us a Clinton blowout in 2016 - like 49 states/Reagan blowout - it's possible that might have broken the fever.
