“So you would say the same about Biden’s or Bloomberg’s too?”
Absolutely!
I’m not sure what you are referring too about Bloomberg.
But take Sanders, he has been known for his socialist views for decades . It s not a beleif he had “20-30 years ago” Its part of who he is. Even if he ran saying oh I dont believe that stuff anymore, it would be absurd to believe him.
Its one thing changing your mind about a specific item, say Trump used to be pro – gun control and now changed his mind. Fine nothing wrong with that . but to change your whole persona at age 70? yeah I don’t buy it
