The law regarding electioneering by any election official can be found
at this page: http://www.legis.state.wi.us/statutes/Stat0012.pdf
It is Chapter 12 of the Wisconsin statutes, "Prohibited Election Practices."
Here is a key excerpt:
"12.03 Election day campaigning restricted.
"(1) No election official may engage in electioneering on election day.
"(2) No person may engage in electioneering during polling
hours on any public property on election day within 100 feet of an
entrance to a building containing a polling place. This subsection
does not apply to the placement of any material on the bumper of
a motor vehicle that is located on such property on election day.
"(3) A municipal clerk, election inspector or law enforcement
officer may remove posters or other advertising which is placed
in violation of this section.
"(4) In this section, 'electioneering' means any activity which
is intended to influence voting at an election."
So the basic answer is that no election official, including a deputy
voter registrar, can electioneer on election day. I found no
reference to indicate that election officials can't electioneer on
I hope this fully answers your question.
