2 files:

• 20101102__oh__general.csv
• 20100504__oh__primary.csv

There are incorrect districts in 20161108__oh__general__precinct.

I'm not sure if it's incorrect across the board, but I discovered it in the case of OH-01 and OH-02 both crossing into Hamilton County.

For example:

Hamilton,BLUE ASH 1-A,AAA,Representative to Congress,1,R,Steve Chabot,0
Hamilton,BLUE ASH 1-A,AAA,Representative to Congress,1,,Sholom D. Keller,0
Hamilton,BLUE ASH 1-A,AAA,Representative to Congress,1,,Kiumars G. Kiani,0
Hamilton,BLUE ASH 1-A,AAA,Representative to Congress,1,D,Michele Young,0
Hamilton,BLUE ASH 1-A,AAA,Representative to Congress,2,,Janet Everhard,0
Hamilton,BLUE ASH 1-A,AAA,Representative to Congress,2,D,William R. Smith,157
Hamilton,BLUE ASH 1-A,AAA,Representative to Congress,2,R,Brad Wenstrup,364

I do not believe the Hamilton,BLUE ASH 1-A,AAA precinct should include any District 1 candidates.

I checked the 2016 Hamilton Country source file from the sources repository, and the aforementioned Blue Ash district appears on the District 2 sheet, but not in the District 1 sheet.

I also grabbed an export from the Hamilton County board of elections and confirmed that the precincts don't accommodate multiple districts.

The issue happens in the other direction as well:

Hamilton,CINCINNATI 3-A,ACZ,Representative to Congress,1,R,Steve Chabot,72
Hamilton,CINCINNATI 3-A,ACZ,Representative to Congress,1,,Sholom D. Keller,0
Hamilton,CINCINNATI 3-A,ACZ,Representative to Congress,1,,Kiumars G. Kiani,0
Hamilton,CINCINNATI 3-A,ACZ,Representative to Congress,1,D,Michele Young,618
Hamilton,CINCINNATI 3-A,ACZ,Representative to Congress,2,,Janet Everhard,0
Hamilton,CINCINNATI 3-A,ACZ,Representative to Congress,2,D,William R. Smith,0
Hamilton,CINCINNATI 3-A,ACZ,Representative to Congress,2,R,Brad Wenstrup,0

The Hamilton,CINCINNATI 3-A,ACZ precinct should be a District 1 precinct, but should not be a District 2 precinct.

I found that all precincts in Hamilton County in 20161108__oh__general__precinct appear for District 1 and District 2 candidates.

It's entirely possible that this issue extends beyond Hamilton County, but I haven't yet had a chance to investigate.

From Ohio Secretary of State's Office (emphasis added by me):

On January 18, 2019, the LaRose Administration became aware that the Miami County Board of Elections (“Board”) had not counted 6,282 early in-person absentee votes cast in the November 2018 General Election. Upon discovery, our administration immediately launched an investigation into the Board and placed the Board under administrative oversight. Our administration instructed the Board to reconcile the in-person absentee votes and amend its official results. The Board certified its amended results on January 22, 2019, and amended its Absentee Supplemental Report on February 13, 2019. Below is the amended data from the Board underneath the election results as originally certified and reported.

The 2018 data currently in this repo was merged on December 30, 2018. Miami County values should be updated to reflected these amended results.

County-level data only, HTML table is here. Things to know:

The data is formatted a little weird in the 2016 precinct results.

Some examples:

• Butler,FAIR2WD1,AAB,President (at-large),,R,Donald J. Trump,93 (is at-large desirable?)
• Butler,FAIR2WD1,AAB,President (district),8,R,Jeb Bush,1 (are district and 8 desirable?)
• Butler,FAIR2WD1,AAB,U.S. House,"08 (idle ", leading zero)
• Unexpired Term Ending 01/03/2017",R,Matthew Ashworth,1 (Probably erroneous data?)
