I believe this subject was raised before on this list,  but looking through
the archives did not generate any hits.

What states allow for challenges by election officials to voters at the
polls?  In particular, I am looking at citizenship requirements, and how
naturalized citizens are treated.

This is related to the issue that Dan Tokaji first raised.  <
