some districts contain results for multiple districts

[NickCrews]

Look at all the unique districts that are present in a single precinct. Let's only look at STATE HOUSE offices because we can be sure that every precinct should only be voting for a single house district. Maybe this is also a problem for other offices, but that's out of scope for now.

(I can provide more complete/different code snippets if you want)

t22.filter(
    _.office == "STATE HOUSE",
).group_by(
    "state_po",
    _.county_name.fillna("NULL").name("county"),
    "precinct",
    "office",
).agg(
    districts=_.district.collect().unique(),
).filter(
    _.districts.length() == 2,
)

Some precincts are PROVISIONAL, and so probably are expected ot have multiple districts. But others look like regular precincts. If we zoom into one precinct, note that district 32 and 33 are present.

t22.filter(
    _.state_po == "AL",
    _.county_name == "TALLADEGA",
    _.precinct == "LIMBAUGH COMM CTR",
    _.office == "STATE HOUSE",
)

Is this actually a problem, or is this expected?

Those precincts appear to be actual polling places, and in the raw data, one state house race will commonly have votes from multiple polling places (including the overlap one you've identified). So in this case I believe the data are teaching us that, in Talladega county Alabama, a polling place will often draw from a region that spans multiple state house districts. It isn't a cleaning problem because it's in the raw data, and I see no reason to think it's a problem with the raw data.
