Editorial.  When Florida lawmakers authorized the expansion of
database searches for voter registration purposes, they put into place a
mechanism that would produce exactly this result: finding voters who
had died in other states but whose passing was not previously noted by
local elections officials. In Florida, that’s an all-too-common
occurrence, because many older voters live in other states during the
summer months but have Florida addresses come November, when Election
Day arrives.

What the showing from Florida reveals is that
increased linking of databases will help to clean up voter registration
rolls much more efficiently for cases where people have multiple
addresses or part-time residences. States such as Arizona and Texas also
face many instances of split residencies.
