This is about the election on Nov 7, 2028 (in 4 years).
Following the definition of "almost president" in my blog. For each of the Democratic and Republican primaries
The person winning the most delegates based on state contests
The runner up on delegates, but only if the winner is not a former president
Additionally, these unlikely conditions could trigger
The person nominated at the convention. This covers "dark horse" primary winners.
The first place candidate from the first ballot at the convention
The second place candidate from the first ballot at the convention if the first place candidate isn't the winner or runner up on delegates
Any candidate and their running mate if they get at least 10% of the popular vote in the general election or win at least one electoral vote in 2028. Faithless electors do not count.

2025 Jan 24 - Edited to clarify that e.g. Kamala Harris is a dark horse candidate but this wouldn't cause Dean Phillips to become an almost president.
