From an article at Axios:
Some tools at McConnell's disposal:Demanding roll call votes on procedural points of order, forcing Democratic senators and Vice President Kamala Harris — the tie-breaking 51st vote — to live on standby at the Capitol.
Unnecessary quorum calls, pausing Senate business while the secretary issues a roll call vote to ensure all 100 senators are present on the floor. It only takes one member to call for it.
Rotating Republicans onto the floor for hours-long debate about motions and bills — reminiscent of the technique illustrated in the 1939 movie “Mr. Smith Goes to Washington."
Asking Senate secretaries to read through lengthy bills and amendments, similar to what Sen. Ron Johnson (R-Wis.) did before a vote on President Biden's coronavirus relief package — which took more than 10 hours.
Senate GOP aides say they could introduce 2,000-page substitute amendments to make the process particularly tedious...
"The Senate convenes. Quorum call. The presiding officer asks for consent to forgo reading yesterday’s journal. Republicans object. Roll call vote. The officer asks for consent to speed through 'morning business.' Republicans object."
"Democrats move to get on an issue. Point of order. Roll-call vote. Quorum call. Republicans object to the motion. Roll-call vote. A speech. Quorum call. Etc., and so on, until adjournment."
The other side: Democrats insist they've heard it before, and their supporters are sick of McConnell's rhetoric — especially after he changed the filibuster rule to let President Trump fill three Supreme Court seats.
