## Analysis

Discarding Agent 1 (no research, 50% default), the remaining 7 agents cluster tightly between 26-36% with adjusted mean ~31%. All agents identified the same core dynamics: Collins trails Platner in polls but has a proven track record of outperformance, the national environment is hostile to Republicans, and the Democratic primary is the key variable. The ~4% edge over market price (30% vs 26%) is below the 5% threshold for trading, especially given 8 months of uncertainty remaining. The evidence is strong and specific but points in both directions - Collins' historical resilience vs. structural Democratic advantages. Multiple agents noted that if Mills somehow wins the primary, Collins' odds improve dramatically to near coin-flip, but Platner is heavily favored. The market price of 26% is slightly low but within reasonable range given the weight of evidence against Republicans.

## Key Evidence

Collins trails likely Dem nominee Platner by ~6.5 points in RCP average, but has historically outperformed polls by ~10 points (2020). Democratic primary outcome is the decisive variable - Collins is tied with Mills but trails Platner significantly.

## Risks

If Platner's vulnerabilities (Nazi tattoo, controversial posts) become major general election liabilities, Collins could outperform current polls significantly. Conversely, if Collins' 96% Trump voting record sticks in a bad midterm environment, she could underperform even current polls.
