FAQ
Reader questions
How often is polling data updated and what triggers an adjustment in the tracker?
Data is refreshed regularly to reflect new surveys, methodological refinements, and response to real world events. Adjustments are triggered by changes in sample quality, weighting approach, or disclosure of sponsor influence.
What sources are considered reliable and how are questionable polls filtered out?
Only pollsters with transparent methodology, clear field dates, and verifiable sampling frames are included. Outliers are downweighted rather than removed, and persistent anomalies are noted in methodology notes.
Can these metrics predict nomination outcomes, and what limitations should readers note?
While informative, polls measure current sentiment and do not capture turnout mechanics, delegate rules, or unforeseen shocks. They are best used alongside news analysis and coalition assessments rather than as definitive forecasts.
How does the platform handle late breaking information or rapid changes in the race?
Emerging information is incorporated swiftly, with version control and timestamps to ensure traceability. Significant narrative shifts are flagged through methodology updates and explicit change notes.
