2008 Presidential Primaries at a Glance


This "at a glance" look at the Presidential Primaries simply lists the winner (and, in many cases, the candidate who came in second) in each Primary in chronological order. It seems a quick method of discerning the progress of the eventual presidential nominee of the given Major Party (along with that of any significant challengers to that nominee) as the Primaries have progressed through time.

In fact, [presidential] primaries have been much more likely to sow division than unity, and most likely to leave things as they are [re: a potential consensus nominee identified prior to the earliest presidential primaries and caucuses]--

  • state-party. T indicates a tentative date.


  • PR indicates a Party-run Primary.

% Key

  • If a presidential contender wins 75.5% or more of the primary vote, the second place finisher is not listed.
  • U means that this presidential contender- or his/her delegate slate [depending on the type of Primary]- ran in the Primary unopposed (that is, with no other presidential contenders appearing on the ballot but him/her). Please note that write-ins do NOT count as such "other presidential contenders 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 presidential contender has failed to gain at least a majority of the primary vote, the winner of the primary and the contender who came in second are both listed with their respective percentages of the primary vote rounded up or down to the nearest whole integer.
  • P indicates Primary cancelled / nomination by default because nominee was the only presidential contender 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).
