Turquoise Blue - "After Chamberlain comes... Anthony Eden?"
I know this isn't the promised The Quiet Death of Socialist America, but I liked it and thought it would go well here.

Harold Macmillan mused forming a centre-left Social Democratic Party in the 1930s out of moderate Labour and some of the Liberals, plus presumably one or two Tories including himself. He had an admiration of old Liberal leaders such as Asquith and Lloyd George as well.

Polls were held to see if a "War Party" led by Anthony Eden would be popular, and the poll turned out 50/50 split.
This is basically merging the two ideas together, along with a sneaky inclusion of a thirty-years-earlier Alliance.

"After Chamberlain comes... Anthony Eden?"
Neville Chamberlain (Conservative, then Conservative-War-Labour-Liberal-Social Democratic-National Whatever coalition) 1937-1939
Anthony Eden (War-Conservative-Labour-Liberal-Social Democratic-National Whatever coalition, then Unionist transitional government) 1939-1945
Harold Macmillan (Social Democratic-Liberal coalition) 1945-1955
1945: def. Anthony Eden (Unionist), Herbert Morrison (Labour), Archibald Sinclair (Liberal)
1950: def. Malcolm MacDonald (Unionist), Aneurin Bevan (Labour), Archibald Sinclair (Liberal)
Alec Douglas-Home (Unionist majority) 1955-19??
1955: def. Harold Macmillan/Archibald Sinclair (SDP-Liberal Alliance), Aneurin Bevan (Labour)
