You know, I think i'd be easier to have him as Eisenhower's VP and just have Ike have an earlier, more severe heart attack, or get into some sort of accident. But whatever.
It seems that Nixon moved farther right of center as he got older, this Nixon is probably not too far to the right of Eisenhower, probably more progressive than 1960 Nixon and certainly more than 1968. So interesting POD.
Nixon's interest in foreign policy is still there, so maybe earlier detente? Hard to tell, a lot depends on who succeeds Stalin, or if he even dies around the same time.
On domestic policy I think he wouldn't be much different from Eisenhower, maybe more weight of this department is shifted to VP.
I'd be interested in what others think of this too.
