Theory Briefing
- Senators who survived Trump's purge attempts may be less willing to back his agenda, weakening his own legislative leverage.
- Demanding loyalty through primary threats can hollow out a party's governing coalition, leaving a leader with allies who are fewer but no more reliable.
- The 2026 midterms loom as the next test of whether Trump's Senate reshaping strengthens or further fractures Republican unity.
- Purging internal critics can shift power toward the executive short-term but create unpredictable resistance when key votes are needed.
