Linky?
There is no such discreditation. It's a fact, polls done in the Spring of 1980 said Carter would swamp Reagan in November
Carter was so excited about how easily he was going to beat Reagan when he became the presumptive nominee, he literally laughed at how simple it was going to be.
Only a delusional Cruzer would say the kind of thing she did. As Reagan once said, there's so much of what they know that isn't so.
Delusional Cruzers have this one dangerous aspect: willingly, or unwillingly, they want Hillary to finish the destruction the bamster has set in motion. They think only bitter thoughts about their "principled conservative" not being in the white house, so bitter they would rather see Hillary win so they can be snarky in the future.
I used to feel sorry for her, now I suspect she will ride the lightning. When she goes off to watch for the green flash on a beach afterwards, sadly, the green flash will be her and she still won't understand.
