Adding ward-level data via Open Data Portal/ArcGIS about openelections-data-wi

Hi @pjrule,
Check out #21 as well; @epaulson was able to do some cool things with the LTSB data you linked to.

There are some drawbacks to the LTSB data to be aware of:

• It has ward-level vote counts, but those are statistically disaggregated from the reporting units that the WEC publishes. Meaning that LTSB doesn't really have finer detail, they're just estimating.
• To apply 2017 ward boundaries to 2002 election results for example, LTSB has to further disaggregate the results based on the 2002 ward shapes, and then aggregate them according to the 2017 ward shapes. This means that some of their results don't match the WEC-certified results.
• They also only include the biannual elections, while WEC publishes results for all federal and state elections.

So using LTSB data for the Openelections project would involve trade-offs. Maybe @dwillis would have more background on whether contributors to other states' repos have had to decide between this kind of disaggregated data vs. certified results.

Interesting! I didn't realize that the LTSB data is disaggregated. With that in mind, it seems like it's probably better to stick with the WEC data in this case.
