but #1 .. I do not live in the area and have no knowledge of
Ohio election practices, boundary changes, precinct-specific
behaviours etc, and local politics.
That said, I am a Canadian who has spent more than 20 years
working in the election planning and delivery business here in
Canada and abroad.
There are many legitimate reasons why these numbers could defy
logic:
1) The number of registered voters is wrong
# 1 Possible Reason:
- very poor registration management (ineligible or
inactive voters not being purged from the roll)
2) The estimate of eligible voters is wrong. Estimating
population growth is not an exact science and is
prone to errors in methodology, mathematics and
typos and REALITY.
Take Nobe County, Ohio for example. According to the
US Census, Noble was growing at a very rapid pace.
In a 10 year period it increased its population by
24% then suddenly in the 38 month period between
April 1, 2000 and July 1,2003 it seemingly
decreased its population by 4 persons (recorded
as Z on the Census site). Now that didn't make sense
to me until I spied the % Female population for 2000
--- its only 43.3% !!!!!!!! ...
I follow the bread crumbs wherever they take me and this
one led me to ...

Having said that I will continue my search at the poll-level
because that's where my experience and instincts lead me.
Nevertheless, it is an equally important exercise to look at
all other levels of granularity -- higher levels: precincts,
counties and lower levels: machine level.
