I suspect Pfaffenberger is in a NY State of Mind.
NY is the last state using lever machines. It's threatened both by the Bush-DoJ to change them out, and by a soon to be filed lawsuit arguing to keep them.
DREs, while not outlawed, aren't effectively an option in the state, and many others. Perhaps the author got ahead of himself paying scant attention to DREs, mentioning them only as a "failure" in the article's opening.
Pfaffenberger does refer to Jacob Myer's, and other fairly well known arguments against HCPB in the days of old. Though done so without specific citation, you wouldn't need much time to become familiar with them.
Looking more deeply in the article, the author, in arguing against WIDESPREAD use HCPB says:
Put simply, the Australian system's defects were too severe.
Myers, who had traveled abroad to study the Australian system up close, found that there were unacceptably high numbers of voided ballots due to voter mistakes (voting for too many candidates, making an erasure, or making an extraneous mark on the ballot). In any close election conducted with Australian ballots, the number of invalidated ballots would probably exceed the margin of victory, calling the election's validity into question.
Emphasis mine. All will recall FL 2000 and realize this is only so different.
He continues;
After all, in the US, election officials are often openly partisan. The 2000 recount battle in Florida made that all too apparent. Did partisanship creep into their decisions about a given ballot's validity? Or if they didn't like the vote it contained, would they spoil it? Election officials have pulled off such tricks right under the noses of election observers, time and again.
The "Stuffer's Ballot Box" may be what he had in mind by "right under the noses of election observers".
But Pfaffenberger doesn't condemn HCPB as much as the Harris Blackwells of the world. Reasonably, he observes;
To be sure, the HCPB system can work well, as it does in Canada, Switzerland, and some areas in the US, provided that elections are administered by professional, nonpartisan officials, but in the 1890s, the movement to professionalize and depoliticize election systems was still in its infancy.
Returning to HCPB might work well in areas with lots of oversight, but in contrast to other stable democracies, this movement has made little progress in the US. Throughout most of the country, today's election system has more in common with that of the 1890s: It's inadequately supervised, insufficiently professionalized, and all too often staffed with openly partisan officials.
Under these circumstances, what voting machine backers believed a century ago still holds true: It just isn't wise to let people count ballots.
My take on this includes the idea that expecting the fed to mandate HCPB nationally is merely entertaining. Posting endlessly on an internet forum, as some do, about abandoned national legislation for HCPB is a waste of everybody's time...time better spent as it is by the likes of Dave Berman attempting to turn California's rural Humboldt county into a HCPB jurisdiction.
Or join the lawsuit to retain NY's lever machines.
