The Briefing:
- Michigan's 2026 Senate race between Democrat Abdul El-Sayed and Republican Mike Rogers has attracted more than $205 million in disclosed outside spending — making it the most expensive Senate contest in state history.
- El-Sayed holds a consistent polling lead heading into Election Day, with prediction markets placing his odds of winning at 73–79% as of October 31.
- Michigan is the only genuinely open Democratic-held seat in a state Donald Trump carried in 2024, making it the GOP's clearest path to expanding its 53–47 Senate majority — a path that polling suggests is closing fast.
