What Rallybase does not know here
- The state and local offices and ballot measures on this ballot. Rallybase reads federal filings from the Federal Election Commission; a state does not publish its whole ballot there, and we have not read one elsewhere.
- When early voting closes in Illinois. We hold the opening date and not the closing one.
- The registration deadline for this state. We hold it for some states and not this one, and a deadline guessed from another state is a date somebody would miss by.
