This is about the election on Nov 7, 2028 (in 4 years).

Following the definition of "almost president" in my blog
- Either major party candidate and their running mate.
- The runner up in either primary, but only if the winner is not a former president.

Additionally, these unlikely conditions could trigger
- Both the first and second place candidates from the first ballot of a primary in the event that neither of them is the winner. This covers "dark horse" primary winners.
- Any third party candidate and their running mate if they get at least 10% of the popular vote or win at least one electoral vote in 2028. Faithless electors do not count.
