Except you have no clue who they might be because you have already branded the majority as being racist.
No he didn't.
He voted TRUMP voters racist. The ones that he wants to reach are the ones who didn't vote at all, for either party.
It's funny: support for Trump actually dropped among whites in 2020 compared to 2016, so I think you can chalk some of that up to the non-racist parts of the 2016 Trump base switching over.
I also don't understand the idea that someone whose big concerns are material getting so offended by being lumped in with racists that they would vote against their own interests. It's totally irrational behaviour, so why would anyone want to cater to that?
Finally, isn't it wild that Democrats are always the ones who need to reach out and understand GOP voters and try and win them over, but the GOP never ever does the same for Democrat voters?
