Meh. Polls mean very little.
What does matter is Trump's election history. 2016 narrowly won a few swing states for Electoral College victory, but lost popular vote. 2020 lost bigly in popular vote AND Electoral College. Bichd and whined like a child "rigged!". Went to GA and demanded absolute loyalty from GA senate candidates. BOTH lost. Since then, his endorsement of a candidate makes them more likely to lose. Abortion stance has been a losing position, so he keeps trying to change it. His constant angry and divisive rhetoric is not winning new voters, just hanging on to his angry minority.
His hopes of beating Biden are
1. Cheat. Not out of the question.
2. Hope for apathy from Democrat voters.
3. Biden health problem. However, if that happened and they replaced him with a younger candidate, Trump could still lose.
