Majority Party Control
When the same political party controls both the Senate and the House, it typically leads to increased legislative productivity and the passage of more bills that align with the party's priorities.
One example of this was the period of Democratic control in Congress during President Barack Obama's first two years in office (2009-2010), when the Democrats held majorities in both chambers. This period saw the passage of significant legislation such as the Affordable Care Act (ACA), also known as Obamacare. The ACA was a landmark piece of healthcare reform that expanded health insurance coverage to millions of Americans.
Another example is the period of Republican control of the Senate from 2015-2016. During this period, the Republicans were able to pass several bills that aligned with their conservative agenda, including tax cuts and the appointment of conservative judges.
Divided Control
When there is divided control of the Senate and the House, it can make it more difficult to pass legislation, especially controversial or partisan bills. This is because the two chambers must reach a consensus on any bill before it can be sent to the president for signature.
One example of this is the current situation, where the Democrats control the Senate and the Republicans control the House. This divided control has made it difficult to pass major legislation such as the Build Back Better Act, a large social spending bill that was a key priority of President Biden. The bill has been debated and revised multiple times, but has not been able to pass either chamber in its current form.
Filibuster
Another factor that affects the impact of Senate control on policymaking is the filibuster, a procedure that allows senators to prolong debate and prevent a vote on a bill. This means that even when one party controls the Senate, they may still struggle to pass legislation if the minority party uses the filibuster to block it.
The filibuster has become increasingly common in recent years, making it more difficult to pass legislation in the Senate. This, combined with divided control of the Senate and House, has resulted in a decrease in the number of bills passed by Congress in recent decades.
In summary, control of the US Senate can have a significant impact on legislative policymaking. When one party controls both the Senate and the House, it typically leads to increased legislative productivity and the passage of more bills that align with the party's priorities. However, divided control and the use of the filibuster can make it more difficult to pass legislation, even when one party controls the Senate.
