The state delegation that disagreed with itself most

Of every state’s delegation, the Pennsylvania contingent split the most this fortnight: 18 roll calls where members of the same state voted differently from each other. Sample:

• PN999-4 — 2026-09-17
  Yea: David McCormick (R)
  Nay: John Fetterman (D)
• PN999-4 — 2026-09-17
  Yea: David McCormick (R)
  Nay: John Fetterman (D)

Why this matters

When a state’s delegation splits internally, it’s often a signal of intra-state political pressure — different districts, different coalitions, or a shift in alignment around a specific issue. Coverage tends to focus on party-line votes; intra-state splits are quieter but can reveal where coalitions are realigning.
