31 members of the House Freedom Caucus. -- Formally dropped the hammer.
95 members of the House Progressive Caucus. -- Still "discussing". AOC, Ilhan Omar, Rashid Tlaib, and Ayanna Pressley are pushing buttons most likely.
1 Justin Amash. -- Still angry.
That gives you 127 votes. The goal is 218. If those three groupings come out fully against the budget deal *as expected* and another 91 come out against it then it is toast. These can be found fairly easily, I think, among just the GOP.
