I don’t recall specifically hearing this scary-sobering factoid, but I’ll toss this list out there.
1945-1953 – Democratic Party
1953-1961 – Republican Party
1961-1969 – Democratic Party
1969-1977 – Republican Party
1977-1981 – Democratic Party
1981-1993 – Republican Party
1993-2001 – Democratic Party
2001-(at least 2009) – Republican Party
I started with 1945 because, while Franklin Roosevelt was elected in 1944 to a 4th term, his Vice President, Harry Truman, assumed the office near the beginning of the term and thus the term was more his than Roosevelt’s, and the 22nd Amendment term-limiting Presidents was ratified during Truman’s administration, though it did not apply to him.
What is scary-sobering is only once in the last 63 years (64 by the time President Bush is officially term-limited) has a party maintained control of the White House for more than 8 years, and the party in control now is the Republican Party. Of course, the one long-term outlier is the Republican Party.
