Unbelievable. A Communist, Henry Wallace a heartbeat away from the Presidency.
The other person who was seriously considered in 1944 was James Byrnes of SC, who was certainly very competent. I have run across two explanations for why Byrnes was passed over--that as a South Carolina Democrat he was tied to support for segregation, and that as a former Catholic who had become an Episcopalian, he could have cost the party some Catholic votes.
