Not opponent! ENEMY!!! We all should be hand in hand like the photo! Even the loser of a primary should.
Primaries only weaken candidates by giving the enemy their opposition research for them and, at least with us, the people who supported the loser in the primary carry that grudge into the general election.
I supported Bernie Sanders in 2016 completely. When he lost, I did what any sensible candidate did: nursed my wounds for my candidate not winning and supported HRC completely. Did the same in 2024 when Biden dropped out due to whatever stupid reason was hammered home because of the first debate performance. I supported Harris COMPLETELY. Unfortunately, a lot of Bernie supporters are angrier with the Democrats than the Republicans which I have no idea why, so they either stay home or vote third party and help Republicans. Which is why I've called them faux-gressives for at least three decades!
I want John Fetterman primaried, but I know he will go LOW on the candidate that runs against him. He will do the Republican's research and attack ads for them. So WHEN he loses (and he will), the Republicans will continue the attack ads he made. Happens ALL the time. Sinema did it to Gallego and the Republicans in Arizona used her ads to attack Gallego. Not the ads specifically, but the ideas from the ads.
Primaries are to show how you will better represent the party. They turn into mini-elections that destroy the winning candidate. The Republicans now are proving that because these two fools on the Republican side are trying to destroy each other by showing how "not-as-Trumpy" the other is. It will damage them in the general and Ossoff already has the attack ads lined up because of it.
