One way to get around that 60-vote threshold and avoid the threat of a
filibuster is budget reconciliation, a tool made possible because of the Congressional Budget Act of 1974.
Reconciliation allows the party in control to pass legislation with a 51-vote simple majority in the Senate. The aim is to make it easier for Congress to make adjustments to laws that either bring in revenue or change spending levels.

Reconciliation is a two-stage process.
It starts with a budget resolution that gives instructions to congressional committees to write legislation that achieves certain budgetary outcomes. For example, a resolution might include instructions to the Committee on Armed Services to report changes in laws within its jurisdiction that result in increasing or reducing the deficit by a certain amount.
Once the budget resolution passes out of committee, the committees that received instructions get to work.
The Budget Committee then incorporates all those bills into one big bill that's considered by the House and the Senate.
If there are disputes between the chambers, they have to resolve them.
Vote-a-ramas can be dramatic and drawn-out affairs where senators take up a marathon of amendments ahead of a final budget vote.
They begin in the Senate when debate on the bill ends. Senators essentially keep offering amendments on the bill until they run out of amendments — or steam — and decide to stop.
It is a rare chance for the party in the minority to bring legislation to the floor and is an opportunity for senators to try to undo parts of the budget resolution through objections known as budget points of order.
There are two vote-a-ramas in the course of the reconciliation process: one on the budget resolution, which is less consequential, and the second on the final proposed legislation itself.
"The amendments that happen in the final legislative package are really important — you're playing with live ammunition when you're on that final stage of reconciliation," said Donovan.
There are limits to budget reconciliation. It's used to make changes to the debt limit, changes to mandatory spending or adjustments in revenues. It cannot be used for discretionary spending.
There's also what's known as the
Byrd rule, named after former Sen. Robert Byrd of West Virginia.
The rule allows anything determined not to have a direct budgetary consequence to be removed from the bill. The goal behind this is to prevent reconciliation from being used for measures unrelated to the finances of the federal government.
In other words, reconciliation is about money going out from the federal government and the money it takes in.
If a senator thinks a provision in the bill doesn't pass muster with the Byrd rule, the senator can raise a "point of order." The Senate parliamentarian advises the presiding officer on whether the provision violates the rule.
This could include anything that doesn't result in changes to spending or revenues, doesn't cause changes to Social Security or doesn't raise the deficit beyond the point of the budget window, which is usually 10 years.
