WI: Tyler survives his illness and takes his seat in the Confederate Provisional Congress. Instead of electing Jefferson Davis as President the CPC elects Tyler instead. Tyler of course has executive experience, a former US President leading the Confederacy is a huge political boon, and Tyler might have pursued a more peaceful solution to the Fort Sumpter dilemma than Davis did.
How would this alternate timeline playout? Would Tyler keep the CSA from firing the first shot of the war, would the war be avoided entirely (stretch I think), could Tyler get recognition and support from Britain faster than Davis?
