Members of the small group believe that about 50 or 60 House Republicans are opposed to the House leadership’s current plan (a CRomnibus bill that passes several long-term appropriations bills but leaves the Department of Homeland Security operating on a short-term continuing resolution of as-yet-undetermined length).

“The thing is that Sessions’ opposition will likely flip the whole [Alabama and Mississippi] GOP delegations (these guys usually would vote for a bloated omnibus) so it won’t necessarily be the same 50 or 60 who voted against other bloated bills like the farm bill,” the lawmaker suggested.

House leaders are expected to partner with Democrats, so the conservative rank-and-file opponents think they’ll need the outside activist groups to ramp up the pressure on other lawmakers.
