What this can't tell you

  • Statewide totals say nothing about who voted or why.
  • Candidates with a party's support under another name (Minnesota's DFL, New York's fusion lines) are counted with that party, as the MIT data's simplified party does; independents stay independents.

How the answer is decided

Each candidate's votes are summed over every ballot line; blank, over- and under-votes are left out. The margin is the winner's share of the votes minus the runner-up's. A runoff, where held, is the result.
