Capitol Coverage Notes

_^|..^.Reasons^.._.^|

Why do these 3 matter for 2026?

• MI‑07 could determine if Democrats retake the House majority. Recent population growth around Lansing and university outreach make turnout decisive.
• CO‑08 is new, suburban, and politically split — only a few thousand votes could swing it.
• NY‑19 serves as a national mood test for independent voters between New York City and Albany — critical to both congressional and presidential ground games in 2026.

These zip codes collectively represent thousands of swing voters in competitive suburban districts, which frequently determine national election outcomes due to their high political engagement and shifting demographics. The zip codes form the core population centers of each competitive suburban district and are critical focal points for campaigns, outreach, and turnout strategies in national elections
