I think that among all those who had allowed their minds to submit to 5 years of intensive operant conditioning to feel that Trump was some sort of existential threat, there are a fraction who allowed the programed reaction to extinguish over the subsequent 3+ years, and started looking at the differences somewhat realistically.
Of the many robots who in 2020 election faithfully voted against Trump (not for Biden), some will not in 2024, because of inflation and the border. Even a 5% swing will be huge.
