I saw a story last week that reported Trump's numbers were dropping because the number of people who voted for him in 2020 and said they would vote for him this year had dropped from 100% to 92%. Meanwhile, Biden's numbers had edged up to 90%. A separate story today gave the phenomenon of Biden return voters as the reason he is now neck and neck with Trump in polls. Their numbers are likely to continue to head in opposite directions.
When Trump is convicted of most, if not all, of the 34-charges against hm, producing the violence from his followers that police say is in the "chatter," they track, he will likely lose many more voters.
I don't subscribe to the NY Times so I cannot read that story and understand the context of the statements reported therein. I just can't help laughing at you quoting that source and presuming the story to be true because it appears to support your position.
