And the opposition can smell the weakness.
The job of Speaker is much too big for little Paul Ryan, who appears to have not one single fight in him.
From the story here in Roll Call:
Minibuses would break up the 12 individual spending bills into a few small packages rather than lump them into a single omnibus bill. Ryan has argued that passing minibuses is closer to regular order and would make the appropriations process more digestible. But he's privately acknowledged that such a strategy would likely result in some bills not getting done, leaving the agencies covered by the unfinished measures in need of a continuing resolution to extend funding through the remainder of the fiscal year.
