The Rats filibustered.
And the GOP did not have the stamina to fight on.
That's the only power that the minority party has.
Thats ‘filibustered’ since it is the replacement rules for a REAL filibuster. Nobody has to stand up and go to the effort and more importantly DRAW THE PUBLIC ATTENTION TO THE ACT OF FILBUSTERING.
In this case the ‘Rats don’t want public attention on this effort by the Republicans to FIX a problem.
