Taft/Truman.

[Uncle Albert/Admiral Halsey]

I see this as a Reid vs. Angle type of battle where Truman wins because of Taft's "extremism." Truman would've been able to portray himself as being harder on communism, especially because Taft's isolationism would've been hard to sell in a general election. In short, Dewey defeats Truman.

[Uncle Albert/Admiral Halsey]

Taft's foreign policy was majorly discredited after WWII in the minds of the American electorate, especially with the looming fear of the Soviet Union. Truman's approval ratings were incredibly low, but Truman would campaign hard and would exploit anti-communist fears, which would be particularly effective given Taft's isolationism. Taft would have to fight charges that he'd be soft on communism. That being said, I don't see Truman doing any better than what I have on my map.
