Adam Jentleson in The Washington Post:
Senate Democrats have a powerful tool at their disposal, if they choose to use it, for resisting a president who has no mandate and cannot claim to embody the popular will. That tool lies in the simple but fitting act of withholding consent. An organized effort to do so on the Senate floor can bring the body to its knees and block or severely slow down the agenda of a president who does not represent the majority of Americans.
The procedure for withholding consent is straightforward, but deploying it is tricky. For the Senate to move in a timely fashion on any order of business, it must obtain unanimous support from its members. But if a single senator objects to a consent agreement, McConnell, now majority leader, will be forced to resort to time-consuming procedural steps through the cloture process, which takes four days to confirm nominees and seven days to advance any piece of legislation — and that’s without amendment votes, each of which can be subjected to a several-day cloture process as well. McConnell can ask for consent at any time, and if no objection is heard, the Senate assumes that consent is granted. So the 48 senators in the Democratic caucus must work together — along with any Republicans who aren’t afraid of being targeted by an angry tweet — to ensure that there is always a senator on the floor to withhold consent.
