Aren't those two statements contradictory? How can DREs have zero
over-votes (that is what I thought) and also be recording overvote rates
of 1 to 2 %?

I still don't get what you're saying.

Yes. I am all for examining undervote rates by county and considering
demographics as well as voting machine types. Let's do it.

Yes, but I would expect to find that the pattern of "differences" between
early votes and election votes might be similar amoung various counties
and "not" expect to find differences (absentee vs. precinct) to vary by
voting machine type unless there was possible shanninigans going on. I'd
be looking to see if the amount or direction of differences were more
similar with op-scan or paperless e-voting counties (correction by
demographics could be looked at and would be more expected than
differences based on type of voting machine).

I have always envisioned this study as studying the patterns of
"Differences" between different types of election results or polls by
county. The pattern of differences would be expected to be the same or
vary by demographics, NOT by types of voting machines, unless there were
some shanninigans.

Is that true in all Iowa counties? Well that is perfect then because the
technology used is the same for both early and absentee, so I would lump
them together for comparing with precinct. Although, you are right that I
couldn't then directly compare Iowa's results with Florida's where early
voting in electronic voting counties is apparently done electronically,
not on paper ballots.

You're right, this study will not be easy, but there may be interesting
patterns that appear. I don't know yet if Florida election results are
available broken out by early voting vs. absentee vs. precinct, but in
Florida, I would lump the early voting with the precinct and compare
versus absentee paper ballot voting, looking at demographics in parts of
the study as you suggest.

If they are lumped together for public release, then that will make a
planned study comparing election results cast using different technologies
impossible. We need them separately.

I know. That is why I have from the beginning considered Iowa as a
'control' state. IMO Florida is the primary state where we might find
differences between electronic and op-scan counties. ES&S voting
machines, from past articles I've read, are the most likely where any
anomolies may occur. Arkansas would be a control state of another type
because it has lots of electronic voting machines that are paperless but
not touchscreen ES&S, so anomolies on paperless e-voting machines of a
different type could show up there as well. Ohio and NJ each have just a
few touchscreen paperless e-voting machine counties using ES&S. If we can
obtain all the numbers, we can look at them in more than one way.

What is typography? What do you mean?

Wow. Well wouldn't we want the final numbers for our study anyway? What
are some examples of why numbers would change?

Thank you.
