As a progressive person, I used a combination of that and The Knock LA's voter guide[2] to get the progressive perspective and then I combined that with Ballotpedia[3] to get a non-partisan view, see more mainstream endorsements, and campaign finance details (California often has too many confusing ballot measures, so when in doubt looking at who paid how much to support a proposition is my usual tiebreaker).

In my ideal world we'll add icons for things like "does this need to be a proposition" (i.e. bond-funded measures; some pension props), a visual indicator of the $$ at stake (state/municipal assessment if necessary), progress bars for how much campaign money was spent on each prop/candidate (a nice proxy for how contentious something is).
What other metadata do you think could be useful?
