They had control of the Presidency and the House of Representatives. I never said they didn’t have that- I said they didn’t have control of the Federal Government.
The Senate was tenuous. Just having 50 Dem Senators (well, that’s not true either because you need to include Independents to get to 50) isn’t good enough- you need 60 votes to have a filibuster-ptoof majority. The Dems just barely scraped that together in 2009, complicated in part by Ted Kennedy’s seizure and eventual death and Al Franken delayed in getting seated due to recounts. They only had 60 votes (still including Independents) from September 24th 2009 - February 4th, 2010. 4 months of controlling the federal government.
That is why when the 2008 financial crisis happened and the Dems wanted to pas a stimulus package in 2009, they had to get Snowe, Collins, and Spectre (who would leater switch parties to get them to 60) from the Republican side in order to get that passed.
They absolutely did not have control of the Supreme Court at any point in the Biden administration and the Republican SCOTUS shut down a lot of what the Biden administration tried to do. I remember checking every day for months to see how they would rule on Student Loan forgiveness, for example.
This is why they have the perception of being powerless- because they’ve pretty much never had the power. The Republicans love people who say the Democrats are useless. They love saying Biden didn’t do what he promised when he DID and the GOP-dominated Supreme Court reversed it. They love being able to stall Democrat legislation and blaming a Democrat president. Everything the Dems have done outside of those 4 months have required careful compromises and negotiation with the GOP to pass.
What times are these?
As I said, they have only had control for 4 months in my lifetime. Before that you need to go back to 1961-1969 with Kennedy and Johnson. I would actually need to do more research to find out whether they had a Supermajority or not, but it’s not even worth looking up because going that far back in time shifts the politics of the parties significantly and is not very relevant to today. The Democratic Party still has plenty of Southern Conservatives all the way into the Carter years.
So I would love to know what pattern you are seeing.
