The poll found 50% of Democrats approve of how Biden has navigated the conflict while 46% disapprove — and the two groups diverge substantially in their views of U.S. support for Israel. Biden’s support on the issue among Democrats is down slightly from August, as an AP-NORC poll conducted then found that 57% of Democrats approved of his handling of the conflict and 40% disapproved.
Johnson was primaried, did poorly in VT and withdrew his nomination. Nominee lost to Nixon.
Ford was primaried, lost to Carter.
Carter was primaried, lost to Reagan.
H.W. Bush was primaried, lost to Clinton, but was also fighting Perot.
So basically every time it’s happened in recent times.
Guess there was few more.

Tldr:
Saying primary challengers make incumbents lose is like saying getting a warning for speeding makes someone more likely to get a speeding ticket
Driving over the speed limit makes both more likely.
So in addition to my point about Carter, and this shouldn’t need to be said, but if a president is so bad that they have to fight a tough primary as an incumbent, they’re probably not going to win their general.
An easy fix is to normalize a primary. Strong incumbents get a second go, and we’re not running an incumbent no one likes in the general if they lose
I think there were legit weaknesses in Johnson, Ford, and Carter.
Johnson because of Vietnam of course. Ford because he pardoned Nixon, and Carter due to the hostage crisis.
Bush was more hurt by Perot than the primary. Buchanan got all pissy over the “read my lips, no new taxes” thing.
