Totals add up the certified precinct results for the precincts inside today's district lines. A precinct split by the district line counts in full, or only in the district holding most of its voters where the linkage assigns it to one, and votes a county reported only countywide (some counties' absentee and early votes) are left out, so totals can differ from an official canvass.
