What if John Tyler, upon Virginias secession somehow takes up the Presidency of the CSA a month after Virginia joins, how would this effect the political landscape?
When the American Civil War began in 1861, Tyler sided with the Confederate government, and won election to the Confederate House of Representatives shortly before his death.
Would Tyler want to be President of CSA, after USA though?
Who'd he pick for Vice President? Assuming he dies in 1862 as per OTL that will be important.
Lets say he dies in 1864
The problem is that Davis was chosen as provisional president when Virgina had not yet seceded--Tyler was therefore not eligible at that time. (The only serious possible rivals to Davis were all Georgians.) And it seems very unlikely that the provisional president and vice-president (Stephens) will not be confirmed by the Confederate electors in November 1861--as was done unanimously in OTL. Even if Davis had somehow died in the interval, Stephens would probably be confirmed as president--don't switch horses ijn mid-stream, etc.
