This is an impossibly heavy lift and ignores many voters’ interests, it will not happen. You are ignoring the third of likely voters who are just voting to Make America a White Patriarchy again (MAWPA).
Trump delivered on his most important campaign promises, cut taxes on the rich and deliver a conservative majority to the SCOTUS.
Biden can't deliver on the most important issues, inflation, Rogue Nations and Student Loan Debt. Most POTUS can't really deliver on the Economy because the Business cycle is much longer than the Election cycle. Usually, economic policies show fruit after POTUS is out of office. They only get credit retrospectively.
If voters, consider the issues when voting it is often based on a single issue. Gun Control, Abortion, Taxes, Immigration, the Environment. On these issues the country is split pretty much 50/50.
I think you misunderstand how Republicans come to see Trump as Honest. I think they take his blunt talk as unrehearsed and authentic. Unlike most politicians who try to keep their worst selves under the hat, Trump has his worst self out on his sleeve. Maybe 49 percent of people hate Trump, but 90 percent of people are sure out political process is broken and want serious change. A not insignificant number are not really opposed to a genocide if the victims are black, brown, Asian, Muslim, Arab, or just plain not White Christians.
The opposition is not stupid, ignorant or uninformed. Many of them are just evil.
