The above chart shows who controlled the House of Representatives, the Senate and the Presidency from 1855 to 2021. As can be seen, there are two periods where one party dominated. From 1859 to 1933 the Republican Party dominated. The Republican Party was formed in 1854 and first took the Presidency in 1861 under Abraham Lincoln. During that period, the House of Representatives was under Republican control for 52 out of the 74 years. The Senate was under Republican control for 62 out of 74 years. The Presidency was under Republican control for 52 out of 74 years. Republican control ended with the Great Depression. The Republicans had control of all three (House, Senate, and Presidency) for 40 of those 74 years. The Democrats had control of all three of these for six of those years.
Then the Democrats took control for the better part of 48 years (1933-1981). They controlled the House of Representatives for 44 out of 48 years, the Senate also for 44 out of 48 years and the Presidency for only 32 out of 48 years. There was only one brief period of two years where the Republicans had control of all three and for 30 of the 48 years, the Democrats had control of all three.
We have then had a period of contested control from 1981 to 2021. This 40 year period started with Reagan’s election, although the Democrats retained control of the House. The Republicans controlled all three for only six years during that time while the Democrats controlled all three for only four years of that time. The rest of that time, for 30 out of these last 40 years, control of the government was contested, with House being under Democratic control for 20 of the last 40 years, the Senate being under Democratic control for 18 of the last 40 years, and the Presidency being under Democratic control for 16 of the last 40 years. This is part of the reason why partisanship has been such an issue.
So, the question is: are we now entering another period of extended control of the national government by a single party? In 1861 the Republicans took control of the Senate and Presidency, having already taken the House in 1859. The next shift happened in 1933 when the Democrats took the House, Senate and Presidency, ending Republican control of all three for 14 years. The shift in 1980 (when Reagan was elected) only took the Senate and Presidency, with the Democrats holding the House for another 14 years and reclaiming the Senate after six years. Now we see Democrats taking House, Senate and Presidency again. Is this the signal for the change, and does changing U.S. demographics ensure that this change sticks (subject of my next posts)?
I will address this further in follow-up “a-political” postings (as I really hate to get into political debates on this blog…they are best done over a beer).
P.S. I did start preparing the first draft of this post before the events of 5 and 6 January (the Georgia senate elections and the certification of the electoral college votes).
