POTUS Robert Lafollette Jr.

Inspired by blackangel's Lafollette thread, Elect him POTUS with a POD of 1939 as a Republican.
Perhaps if FDR dies and the Democratic party swings to the right, and the Wisconsin Progressive Party dissolves and returns sooner to the Republican Party, the liberal wing of the Republican Party gets strenghtned and nominates Lafollette for the following presidential elections.
 
FDR dies, the democratic party has a brutal and contentious primary that results in Huey Long getting the nomination. The republicans right remains impossibly divided, allowing Lafollete to win over the republican liberals and moderates. What is left of the progressive parties endorse Lafollete who runs under a duel Republican/Progressive ticket. Given longs "special" brand of populism much of the democratic base defects to Lafollete who wins a narrow election.
