- Strongest evidence
- The clustering of linked coverage around Burnham and multiple think‑tank/analysis pieces on Healey’s Budget constraints.
- Weakest evidence
- Any claim that attention is converting into voter movement — there is no polling or constituency-level data in the window.
- Gaps
- No recent national polling to test attention‑to‑vote conversion; absence of Electoral Commission or prosecutorial outcomes; no internal party polling or briefing documents in the collection.
- Evidence quality
- Mixed. Core public outlets (BBC, POLITICO) provide firm reportage; some analysis comes from smaller commentary sites — useful but uneven for making causal claims.
- Source diversity
- Moderate. Heavy reliance on BBC and POLITICO, supplemented by think‑tank commentary and niche outlets.
