Key

  • If a candidate wins 75.5% or more of the primary vote, the second place finisher is not listed.
  • U means that this candidate ran in the primary unopposed (that is, with no other candidates appearing on the ballot but him/her). Please note that write-ins do NOT count as such "other candidates on the ballot" but the appearance of "Uncommitted" (or equivalent, such as "None of the Above") on a ballot DOES.
  • L indicates a landslide majority [60.5 to 75.4% of the primary vote] for the winner.
  • D indicates a decisive majority [52.5 to 60.4% of the primary vote] for the winner.
  • N indicates a narrow majority [50.0(+1 vote) to 52.4% of the primary vote] for the winner.
  • Where a winning (or, in a runoff State, leading) candidate has failed to gain at least a majority of the primary vote, the winner(leader) of the primary and the candidate who came in second are both listed with their respective percentages of the primary vote rounded up or down to the nearest whole integer.
  • C indicates the Party's nominee was chosen by a Party-run process other than the Primary (State Convention, Party Central Committee or equivalent).
  • P indicates Primary cancelled / nomination by default because nominee was the only candidate to have filed for this Party's Primary for this office. P also applies to nominees-to-be by apparent Party consensus (i.e. no opposition at an ensuing Convention).
  • R indicates any Runoff which has been scheduled for this date.
