Primaries are controlled by the parties. If they see a candidate they really don’t like *COUGH*Bernie*COUGH*Sanders*COUGH* then they’ll pull out all the stops to prevent that candidate from winning. People like to think Trump wasn’t wanted by the republican party, but his policies aligned 100% with theirs. Similarly, “hope and change” Obama was allowed to win because he was willing to play ball and went back on most or all of his promises immediately after getting elected.

Political parties also legally don’t even have to respect the results of those primaries since they are private organizations.
