So it turns out that you're historically illiterate as well.
Democrats held the WH for 32/48 years during that period and Congress for 44/48 .I was specifically referring to this:
Given that the Conservatives suffered a crushing defeat at the 1945 election and consequentially accepted most of the agenda of the Attlee government in order to remain a viable party of government, it is highly dubious to think about the long postwar period as one of Conservative dominance and using it to link together two actual periods of Conservative dominance (the interwar period and the Thatcher/Major years) is ridiculous given how long it lasted. If we look at all the General Elections between 1945 and 1979 (inclusive on both ends) we find that Labour won five, the Tories won five and one was essentially a 'winning draw' for Labour. No party dominated during the long postwar period: it was a time of intense electoral and political competition. It isn't even possible to understand a lot of government policies - especially the less intelligent ones - without reference to this fact.
