In 1951 Truman tried to convince Eisenhower to run for the Presidency under the banner of the Democratic party. Of course, in OTL he declined and ran as a republican.
But, let's say he accepts Truman's argument and runs for the nomination of the Democratic Party, wins and is the Democratic candidate in the 1952 election. (I know Ike had disagreements on many positions of that party, but let's just go with this for the fun of it.)
Who would have been a likely dem veep for Ike? Maybe an Ike/Stevenson ticket?
Is there anyone the GOP could have successfully run against him?
How does this change the political landscape of the US going forward from the 1950's? Does Nixon's career go anywhere without being Ike's VP for eight years? Can the dems still win again in 1960 after eight years of Ike (and a total of 24 years of democratic presidents)? Does this butterfly away JFK?
