1944:
President Roosevelt was able to carry out his weirdest plan: alliance with liberal Republicans, led by Wendell Willkie, while allowing conservative Democrats (but still not the Deep South) to remaining Republicans. Liberal Party has been formed.
For strictly electoral purpouses Willkie changed his residence to Indiana 
President Franklin D. Roosevelt of New York/Wendell L. Willkie of Indiana (Liberal): 500 ev
Senator Robert A. Taft of Ohio/Senator Styled Bridges of New Hampshire (Republican): 31 ev
1948:
FDR died as in OTL and Willkie became the second Liberal President. Aware of his own health he named Senator Robert M. LaFollette as Secretary of State, then first in the line of succession.
Willkie died in late 1945.
President Robert M. LaFollette of Wisconsin/Senator Claude Pepper of Florida (Liberal): 496 ev
Senator Styles Bridges of New Hampshire/Governor George Mickelson of South Dakota (Republican): 35 ev
1952:
World War II hero General Eisenhower became Republican nominee ans pulled off extremely narrow victory over V.P. Pepper
South, angered on La Follette for civil right bills, voted for GOP
General Dwight D. Eisenhower of Pennsylvania/Senator Andrew Frank Schoeppel of Kanasa (Republican): 275 ev
Vice President Claude D. Pepper/Governor Adial E. Stevenson of Illinois (Progressive): 256 ev
Excellent!
If only had FDR succeeded in taking the Liberals...
