Mike Johnson is navigating one of the tightest House majorities in modern history as Republicans push forward with plans to pass a funding bill for U.S. Immigration and Customs Enforcement and border security agencies during an ongoing Department of Homeland Security funding standoff. With only a razor-thin edge in the chamber, GOP leaders are aiming to pass the measure without Democratic support, a strategy that leaves virtually no margin for internal defections.
At the start of the 119th Congress, Republicans held a narrow advantage after winning 220 seats compared to Democrats’ 215. That margin quickly tightened due to vacancies and the absence of former Rep. Matt Gaetz, who did not return to Congress. With the House requiring a simple majority of those present and voting, the traditional 218-vote threshold becomes a moving target when seats are vacant or members are absent.
