"Monday" was supposed to be the deadline for the Senate to act on the third legislative phase of the coronavirus response. Senate Majority Leader Mitch McConnell (R-KY) set up a process late last week where the Senate would take a procedural vote Sunday to begin debate on a "shell" of a bill. Once there was a deal, McConnell would insert the coronavirus package into the parliamentary empty box. The hope was that the Senate could get 60 yeas to open debate on the coronavirus measure Sunday – then speed up the process and pass the bill Monday. Then the House would have to move to align with the Senate sometime in the near future.

That all melted down Sunday night.

Republicans were always going to need buy-in by Senate Democrats to start debate on the legislation. As we always say on Capitol Hill, it's about the math, it's about the math, it's about the math.

The current Senate breakdown is 53 Republicans and 47 senators who caucus with the Democrats. The procedural vote required 60 yeas to overcome a filibuster.
