Compare the presidencies of Franklin D Roosevelt and Harry S Truman.

That's a very large topic and I won't be able to do it
justice in this space, but here are some comparison points to
consider:

1)  FDR was elected four times, while Truman was
elected once.  It is safe to say that FDR was much more popular, and that popularity
lasted over time.

2) FDR had huge national crises to deal
with: The Great Depression and World War II.  In part, this is what made him a great
President, that he was able to deal with both of them and bring us through it.  Perhaps
Truman would have been a better President if he had been the leader during those
times.

3)  Truman was the first President to deal with the
Cold War, and he responded well.  I believe FDR would have done as well, had he been
healthy by that time.

4)  FDR had a popular war, World War
II, while Truman had a much less popular war, Korea.  It made it harder for Truman to do
much during his Presidency.
