Do not underestimate people' stupidity. The same thing happened here: in 2019 the same party that always did the wrong thing promised to not to do it "this time" and people was so disappointed with our "Trump" (Macri) that they wanted to believe it. And that's a rock-solid psychological force at play: if there's the slightest reason for people in Pennsylvania to not to vote Trump, they will be unavoidably biased to be willing to believe Kamala, actively forcing aside rational thought. I confidently predict people will believe Kamala, not out of rationale, but because they want to do so. They desperately want it to be true. That's an immovable psychological force in a context of despair, specially in a country strongly educated in the concept of faith.
