Discussions of Oscar W. Underwood http://en.wikipedia.org/wiki/Oscar_Underwood becoming president of the United States usually are based on his winning the Democratic presidential nomination in either 1912 or 1924. I don't see either of these as likely. In 1912, like Harmon of Ohio, he was considered a bit too conservative for a convention held at the height of the Progressive Era--though neither man was really a conservative. As for 1924, his nomination was unlikely given the hostility of not only the Klan (which hated him almost as much as they hated Al Smith) but also of some "drys" and progressives who had nothing to do with the Klan. Moreover, even if he had been nominated in 1924, his chances of winning the presidency that year would be negligible in the face of "Coolidge prosperity" and a divided Democratic Party and the likelihood that the La Follette Progressives will hurt Underwood much more than they will Coolidge (just as in OTL "La Follette, the analysts agreed, took more votes from Davis than from Coolidge." https://books.google.com/books?id=rNFpAwAAQBAJ&pg=PA297)
*But* how about Underwood for *Vice*-President in 1912? Both the Wilson and Clark camps wanted his support, and there seem to have been overtures from both camps suggesting he take the vice-presidential nomination, but he turned all such overtures down, making clear that if he couldn't get the presidency, he preferred to stay in the House "as Chairman of the Ways and Means Committee and leader of his party on the floor."

Suppose Underwood had thought otherwise, and had agreed to be nominated as Vice-President on the Wilson ticket. (There might be some grumbling, but nothing like 1924--the bitterness generated in 1924 by the Prohibition and Klan issues was not there in 1912.) Having Underwood on the ticket would probably not much affect the ticket's fortunes in 1912 or even in the close election of 1916. (True, not having Thomas Marshall on the ticket might hurt the Democrats in Indiana, but Hughes carried that state anyway.) There is no particular reason to think that having Underwood as Vice-President would make Wilson's 1919 stroke fatal, but it came sufficiently close to being fatal that almost any "butterfly" could conceivably make it so. In any event, even if this particular way of making Underwood President is not very likely, it is still the likeliest method I know...
So if Underwood does become President, how does he handle the League/Versailles Treaty fight? In OTL, he was a Wilson loyalist on the Treaty, but eventually, when it was clear it did not have the votes, supported the idea of making peace with Germany and leaving the League issue until later:

It seems to me that as an Alabaman vitally concerned with the cotton trade with Europe--which to him required getting *some* peace arrangement ratified as soon as possible--Underwood as President would probably have shown more flexibility than Wilson.
