Ballot measures
Not centered here
Ballot measure committees may be included in overall flows, but ballot measures are not foregrounded as a lead overview module here.
Proof
What jumps out before you click deeper
The homepage should stay broad and defensible: flows, concentration, and filing activity first; deeper rankings and entity comparisons in the runway.
Committees often reveal where money is concentrating first
The first useful surprise for most users is scale. Candidate names may draw attention, but committees are where the statewide picture starts to become legible.
The homepage should communicate that pattern cleanly, then let `/runway` carry the ranked detail and comparative depth.
Browse committees Donor networks can shape multiple contests at once
A relatively small donor universe can set the tone across several committees and candidate-linked efforts at once, even when race-level attribution is incomplete.
That is a stronger homepage message than a miniature donor table. It creates curiosity without trying to duplicate the actual donor browse experience.
Browse donors Reporting waves can quickly change the picture
The third useful pattern is motion. Users should feel that filing waves and reporting bursts are changing the landscape, not just populating a static archive of totals.
The homepage can say that crisply. `/runway` is where we should show which committees, candidate-linked money clusters, and filings are actually driving the surge.
