Winning with Dewey on normal mode is pretty easy if you pick the right answers. I do think the game overestimates Truman's strength though. The IRL result was more of a fluke then a referendum.

I got this result right now by
- Picking Warren as my running mate
- Campaigning in New York and California
- Opposing veto on Taft-Harley bill
- Supporting civil rights, moderate on other social issues
- Regularly attacking Truman on policy (you need to play offense against an incumbent)
