Technically, “reconciliation” is a procedural mechanism which permits the majority party in the Senate to avoid the filibuster on some issues relative to the budget. In a more common sense, “reconciliation” refers to efforts by two adverse parties to resolve differences and move on together.
In the current context, the two meanings are at odds. Which is more important? The Democrats should do their best to harmonize the two by avoiding the use of the reconciliation process and reaching bipartisan agreements where reasonably possible, but the issues facing the nation are too pressing to avoid it altogether. On some looming budgetary matters, such as permanent welfare state expansions and green investments, there is no plausible alternative.
