As Scalia said the House has the power of the purse. The majority in the house, even a majority of one, can decide not to pass an appropriation or forbid spending money on x,y, and as part of an appropriation and no one else can do anything about it.
“The majority in the house, even a majority of one, can decide”
That requires 100% unity, without a single disagreeing vote out of several hundred.
Don’t be silly!
