The 1936 election is one of the most devastating landslides in the history of presidential elections. And in terms of the electoral vote, the biggest landslide at 523 Roosevelt, 8 Landon. Of course, Alf Landon was an unexciting candidate. It's unlikely the Republicans could ever win with a better candidate, or even that a landslide of some proportion wouldn't happen. But of the GOP, who do you think would've performed the best against FDR if they were made the nominee instead of Landon? Note that with this, I am factoring this entirely on the Republican candidate, and not detracting from the incumbent president. Huey Long may survive in this timeline, however at most he can have a third party effort. FDR is still the Democratic nominee. Be realistic with this, which is why it's the candidate who'd perform the best against FDR, not the candidate who can beat him. Bonus points if you don't include Long. Gold star if you actually make a realistic case for the Republican candidate beating FDR
