Boehner ally Rep. Mike Simpson (R-Idaho), a key member of the Appropriations Committee, told The Hill that postponing the debt-limit fight makes it more difficult for appropriators to move their spending bills before the summer recess. . .With the GOP-controlled House and the Democratic-controlled Senate so far apart on their respective budgets, Boehner will have to negotiate spending levels while also dealing with the very real possibility of a government shutdown in the fall.Since Republicans took over the House in 2011, the majority party has had a difficult time garnering a majority of the fiscally conservative conference to support spending bills, let alone more divisive matters such as immigration.Still, Simpson believes that Boehner intends to let the House “work its will” on the measures even if it means relying on Democratic votes to carry the majority of support for those bills.“When you are Speaker, you aren't just Republican Speaker, you are Speaker of the whole House and you need to do what's best for the whole House sometimes that might mean a majority of Democrats and minority of Republicans that pass a bill,” Simpson said.Others disagree. Conservatives on and off Capitol Hill are urging Boehner to embrace the “Hastert rule,” which is named after former Speaker Dennis Hastert (R-Ill.). The rule stipulates that no bill can come to the House floor unless it has the backing of a majority of House Republicans.Some Republicans don’t think that is necessary.“The important thing is to pass something on immigration so we can go to conference with the Senate,” Simpson noted.
