Section 9-206. Canvass of election district returns of general and special elections

The canvassing board shall canvass the votes cast within  the
  county  for  state, county, city and town offices; also the vote cast on
  any ballot proposal.   The canvass by the  county  board  of  canvassers
  relating  to  the  offices of president and vice president of the United
  States,    governor,     lieutenant-governor,     state     comptroller,
  attorney-general,   United  States  senator,  member  of  the  house  of
  representatives, member of the state senate, member of the assembly  and
  any  ballot  proposal  shall  show  in  each election district the total
  number of persons voting at such election, the number of votes cast  for
  each  candidate, the number of unrecorded or blank votes for each of the
  above-mentioned offices and each ballot proposal.  Write-in  votes  cast
  for  president  or  vice president for persons who were not certified by
  the state board of elections as write-in  candidates  for  such  offices
  shall  not  be  canvassed  for  such  candidates but such votes shall be
  canvassed as void votes. If, during the  canvass,  there  shall  clearly
  appear  to  be  any  omission  or clerical mistake in the return for any
  district filed with the board of elections,  the  canvassing  board  may
  summon  the  election officers before the board, and such officers shall
  meet forthwith and make any necessary correction, in  order  that  their
  canvass  may  be correctly stated, but they shall not alter any decision
  theretofore made by them.
