This is pretty interesting, about how they can get this done.
Democrats Plan Push to Curtail Use of Filibusters
WASHINGTON — A band of Senate Democrats signaled on Monday that it would press forward when Congress convenes this week with a proposal to curtail filibusters and other methods of slowing the chamber’s work, but a bit of procedural sleight-of-hand could delay any floor fight over the contentious rules changes until later in January.
<..> In essence, Democrats could put the Senate in recess at the conclusion of Wednesday’s mainly ceremonial proceedings to be highlighted by the swearing in of 13 new senators.
As a result, the Senate would technically still be in the same legislative day when lawmakers returned on Jan. 24, and the backers of the rules changes could proceed at that point if they were not satisfied. Mr. Udall could also seek other guarantees that his right to challenge the rules was not harmed by the delay, which he said could give him more time to build support for his plan.
<..> Besides forcing senators to take the floor to defend their filibusters, Democrats also want to make it harder to stonewall the initial effort to bring a measure to the floor, a step known as the “motion to proceed.” They also want to ban the ability of senators to place an anonymous “hold” on a bill or nomination.
